filter gridview based on dropdownlist selected value
You are not showing where you initialize idTeacher. However, you have to DataBind the GridView in ASP.NET after you have assigned the DataSource: GridView1.DataSource = table; GridView1.DataBind(); // <-- this is missing in your code You should use sql-parameters anyway, otherwise you are potentially open for sql-injection and you should use the using statement to ensure that all unmanaged resources are disposed (even on error): using (var con = new OleDbConnection("ConnectionString")) using (var da = new OleDbDataAdapter("select * from teacher where idteacher=@idTeacher", con)) { da.SelectCommand.Parameters.AddWithValue("@idteacher", idTeacher); DataTable table = new DataTable(); da.Fill(table); // opening or closing connection not needed, done by Fill GridView1.D

Cannot Access DropdownList in EditItemTemplate inside Gridview
The RowEditing event just gives the row index being edited. You need to set the edit row index to the grid and rebind it. And if you need to set a value or need to bind a control inside EditItemTemplate you have to do it in RowDateBound event, as you will be re-binding grid in RowEditing event so the RowDataBound event will also give you the EditItemTemplate's controls. As shown in this answer protected void gv_RowEditing(object sender, GridViewEditEventArgs e) { // grid view's edit index has been changed so rebind it gv.EditIndex = e.NewEditIndex; } protected void gv_RowDataBound(object sender, GridViewEditEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if ((e.Row.RowState & DataControlRowState.Edit) > 0) { ddList.SelectedValue

Postback resets the selectedValue of DropdownList inside GridView
RowDataBound gets fired every time (irrespective of whether the page is PostBack page or NOT). You need to add that if(!IsPostBack) condition around the code where you are performing the databinding for the dropdowns in your RowDataBound event.

Null Exception thrown in dropdownlist selected value inside gridview on button click
If you have a header row, it will always be at the index 0, so you can't test for it not being the header row and having an index of 0, as both checks will return false. Change your index in both your check for adding the DDL, and the code to fetch it. Adding code: if (e.Row.RowType == DataControlRowType.DataRow) { DropDownList ddl; if (e.Row.RowIndex == 1) { // ..... } } Fetching code: GridViewRow row = dgData.Rows[1]; DropDownList ddl = (DropDownList)row.Cells[1].FindControl("ddlCol1");

Android - GridView onItemClick callback not being called When GridView is inside ViewPager
if the goal is simply to get the notification, use OnClickListener instead of OnItemClickListener. Set the listener via setOnClickListener in getView when convertView is null. Otherwise, if you need the extra information that you would get in onItemClick, you can specialize ImageView to set and retrieve the convenience members that you define in the specialized class.

gridview inside gridview... forum functionality
You can't directly access any control inside the gridview from code behind. You have to first make the object of that control. GridView GridView2=(GridView)GridView1.Rows[RowIndex].FindControl("GridView2"); Something like this. Refer this:http://www.codeproject.com/Articles/189997/Gridview-inside-Gridview-in-asp-net-Csharp.

Improve page rendering time having gridview, child gridview and grand child gridview on it
You are creating way too many grids. A grid is an expensive component. You could alter your user interface to allow users to select an Item and bind the inner grid only on selection. This ensures that rather than one grid per row or parent grid, you will have only one child grid displayed at a time.

Getting row of selected DropDownList in GridView cells
You can find the grid view row by finding the grandparent (.Parent.Parent) of your drop down list, because the drop down list is within a cell of the row, which is a part of the row itself, so you need to go two levels up, like this: protected void chooseThemeTypeDropDown_OnSelectedIndexChanged(object sender, EventArgs e) { DropDownList chooseThemeTypeDropDown = sender as DropDownList; if (chooseThemeTypeDropDown != null) { System.Diagnostics.Debug.WriteLine(chooseThemeTypeDropDown.SelectedItem.Value.ToString()); GridViewRow row = (GridViewRow)chooseThemeTypeDropDown.Parent.Parent; } }

How do I set dropdownlist selectedvalue in edit mode but not in gridview?
You have to use TemplateField and within that template you can specify your layout, which could contain multiple fields, and use different controls for Edit/Insert operations, like in the following sample: Listing 1. <asp:TemplateField HeaderText="Toll-Free: Area/Phone #"> <ItemTemplate> ( <%# DataBinder.Eval( Container.DataItem, "A_TollFree_AreaCode" )%> ) <%# DataBinder.Eval(Container.DataItem, "A_TollFree_Number")%> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtAreaCode" runat="server" CssClass="phoneAreaCode" MaxLength="3" Text='<%# Bin

populating DropDownList in a gridview with array elements
You could simply loop it and add the ListItems programmatically: DropDownList drd = (DropDownList)GridView1.FindControl("DrdDatabase"); foreach(string colName in mylist) drd.Items.Add(new ListItem( colName )); However, are you sure that you find your DropDownList via GridView1.FindControl? I assume you get a NullRefernceException there. Then you need to show us where it actually is. If it is in a TemplateField of the GridView you should use the RowDataBound event: private ArrayList ExcelData { get { object excel = Session["exceldata"]; if (excel == null) Session["exceldata"] = new ArrayList(); return (ArrayList)Session["exceldata"]; } set { Session["exceldata"] = value; } } protected void GridView2_RowDataBound(object sender, GridVi

How to set Eval("DropDownList.SelectedItem.text") programmatically to gridview in asp.net c#
In .aspx '<%# DropDownList2.SelectedItem.Text %>' WITHOUT the Eval Or DoubleQuotes. you are just exposing server-side control property and you don't need to use Eval as you are not evaluating an expression from a bound Data-item. You can also use the RowCreated event or RowDataBound for your gridview : protected void MyGrid_RowCreated(object sender, GridViewRowEventArgs e) { //DoWhatever you Need TextBox t = e.Row.Cells[4].FindControl("subject") as TextBox; t.Text = DropDownList2.SelectedItem.Text; }

How do I use a DropDownList in a Gridview Edit Template when the selected value does not mirror sql data?
You don't need to do this in code; the ListItem has both a Text and a Value property: <asp:DropDownList ID="ddlDay" runat="server" SelectedValue='<%# Bind("Day") %>'> <asp:ListItem Value="1" Text="Monday" /> <asp:ListItem Value="2" Text="Tuesday" /> <asp:ListItem Value="3" Text="Wednesday" /> <asp:ListItem Value="4" Text="Thursday" /> <asp:ListItem Value="5" Text="Friday" /> <asp:ListItem Value="6" Text="Saturday" /> <asp:ListItem Value="7" Text="Sunday" /> </asp:DropDownList> The SelectedValue will return the day number, and the list will display the day name.

SqlDataSource makes DropdownList results to one item that is duplicated in the list for displaying in GridView
You've defined your DropDownList in the following way: <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="ProblemDataSource" DataTextField="SkillGroup" DataValueField="SkillGroup"> <asp:ListItem Selected="True">Hardware</asp:ListItem> <asp:ListItem Selected="True">Software</asp:ListItem> <asp:ListItem Selected="True">Network</asp:ListItem> </asp:DropDownList> For a start, you can't have all items selected. Only Hardware will be selected as it's the first in the list. This leads to your second problem; The query you then run is (reduced for brevity): SELECT blah FROM Tables WHERE ([SkillGroup] = @SkillGroup) Which, of course, will be Hardware in your example above.

Nested gridview checkboxes are not toggling when master gridview checkbox is toggled
When you run your first CheckBoxAll_OnCheckedChanged you will be running through each checkbox and changing its Checked to True or False dependent on what the CheckBoxAll has been ticked as. This will not cause a postback on the checkbox per one being run. Instead, while looping through the nested gridview you can call the CheckBoxAdd_OnCheckedChanged sub by just passing the object and same eventargs over to it. For example: Sub CheckBoxAll_OnCheckedChanged(sender as object, e as eventargs) 'Loop through gridview here 'When finding the control CheckBoxAdd just call For each gvRow as GridviewRow in gvStudents.Rows dim CheckBoxAdd as Checkbox = gvRow.FindControl("CheckBoxAdd") CheckBoxAdd.Checked = True 'Or false dependent on CheckBoxAll CheckBoxAl

How to call Parent Gridview's item Id by Nested GridView's Content
Unfortunately, you can't do that. WebGrid will only bind to a single model and because the columns aren't strongly-typed you can't reference a parent class. The solution is to create a ViewModel that contains all of the data you want to represent in your WebGrid and then bind your WebGrid to that ViewModel.

Change the name of column in Gridview on runtime when sorting of gridview is enabled
I'm guessing you're trying to use AutoGenerateColumns? If this is the case why can't you change the column name in the datasource (using "AS" if the datasource is SQL)? Otherwise, your altering the cell text is short-circuiting the ASP.NET functionality which generates the sorting javascript postback. Alternatively you would do this if you don't use AutoGenerateColumns: myGrid.Columns[1].HeaderText = "test1";

Filter GridView with Javascript
If I understand your question correctly, you are looking for something like this: $(function(){ $('#tabela input').keyup(function(){ var val = $(this).val().toUpperCase(); $('#GridView1> tbody > tr').each(function(index , element){ if($(this).text().toUpperCase().indexOf(val)<0) $(this).hide(); else $(this).show(); }); }); }); Essentially, it iterates through the rows in the grid looking for matches, hiding/showing the rows accordingly. In your markup provided inside the tabela, you can simply have one text input instead of 3. Here's a quick demo.

It is possible to use DataTables Column Filter Add-on with a Gridview
In order to add anything to the footer, you need to use TemplateField controls rather than BoundField controls. See http://www.dreamincode.net/forums/topic/222381-insert-data-using-gridview-footerrow/ for an example of how to do this. One thing to note though, the HTML generated by the GridView control will use <td> elements in the footer rather than <th> elements as expected by the DataTables documentation.
