I have a grid view which display records by reading the data from a local database. I want to display a button called view with each record displayed. Simply meaning in each row there should be an asp.net button called view Details.
Here is my grid view code:
<asp:GridView ID="ItemView" runat="server" AllowPaging="True"
AutoGenerateColumns="False" CssClass="list" DataKeyNames="ItemID"
DataSourceID="ADDataSource" GridLines="Both" Width="215px">
<Columns>
<asp:BoundField DataField="itemID" HeaderText="Item ID" />
<asp:BoundField DataField="Item Name" HeaderText="Item Name" />
<asp:BoundField DataField="Item Brand" HeaderText="Item Brand" />
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
</Columns>
</asp:GridView>
I have added a button to delete records and edit records through common field property, but how do i add my own button called view to display in each row as the other 2 buttons.
Thank you.
I managed do it myself.
<asp:BoundField DataField="topic" HeaderText="Topic Name" />
<asp:BoundField DataField="Brand" HeaderText="Vehicle Brand" />
<asp:BoundField DataField="Model" HeaderText="Vehicle Model" />
<asp:BoundField DataField="Year" HeaderText="Vehicle Year" />
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:Button ID="viewDetails" runat="server" Text="View" />
</ItemTemplate>
</asp:TemplateField>

I want to hide a column in a gridview. I use the following code;
dgvTekleme.Columns[1].Visible = false;
but this does not work. (may be it does not work because of using that column in the code)
Is there any solution to hide a column in code-behind
you can do this manually.....
goto asp:gridview tag and in gridview tag set autogeneratecolumn="false"
if you don't want to display some column just don't write that column....
for example if you don't want to display prodId column just erase that line....
and write manually for displaying data like!!!!!!!!!!
<asp:GridView ID="gridview1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="ProdID" DataField="prodid" ReadOnly="true" />
<asp:BoundField HeaderText="ProdName" DataField="ProdName" />
<asp:BoundField HeaderText="Quantity" DataField="quantity" />
<asp:BoundField HeaderText="SupplierID" DataField="SupplierId" />
<asp:BoundField HeaderText="StockLvl" DataField="stocklevel" />
<asp:BoundField HeaderText="MinStockLvl" DataField="minstocklevel" />
<asp:BoundField HeaderText="CostPrice" DataField="costprice" />
<asp:BoundField HeaderText="SalesPrice" DataField="saleprice" />
<asp:BoundField HeaderText="Loc" DataField="location" />
<asp:BoundField HeaderText="ProdCode" DataField="prodtypecode" />
<asp:CommandField ShowEditButton="true" ShowDeleteButton="true" />
</Columns>
</asp:GridView>

I am facing a situation where the selectcountmethod isn't called.
The getdatamethod is called every time, but the count method is not. I also tried to remove the selectcountmethod and set enablepaging="false" and no data is displayed either, even if the dataset is not empty.
<asp:GridView ID="gvGradeDocent" runat="server" AutoGenerateColumns="False" AllowPaging="True"
DataSourceID="odsGradeDocent" DataKeyNames="Id" PagerStyle-HorizontalAlign="Right"
PagerSettings-Position="Top" CssClass="table">
<Columns>
<asp:BoundField DataField="Id" HeaderText="Id" SortExpression="Id" Visible="false" />
<asp:BoundField DataField="DecisionNo" HeaderText="DecisionNo" SortExpression="DecisionNo" />
<asp:BoundField DataField="DecisionDate" HeaderText="DecisionDate" SortExpression="DecisionDate"
DataFormatString="{0:dd/MM/yyyy}" />
<asp:CheckBoxField DataField="Status" HeaderText="Status" SortExpression="Status" />
<asp:CommandField ShowSelectButton="True" ButtonType="Image" SelectImageUrl="~/Images/edit.png" />
<asp:CommandField ShowDeleteButton="True" ButtonType="Image" DeleteImageUrl="~/Images/delete.png" />
</Columns>
</asp:GridView>
</div>
<asp:ObjectDataSource ID="odsGradeDocent" runat="server" SelectMethod="GetDocentGrades"
TypeName="mash.BusinessLogic.DocentGrade" EnablePaging="True" DeleteMethod="Delete"
SelectCountMethod="GetCountDocentGrades"></asp:ObjectDataSource>
Try working with the code sample here:
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.objectdatasource.enablepaging.aspx
Check your query first to ensure that data is coming back. Also set the MaximumRowsParameterName and StartRowIndexParameterName parameters to the corresponding params in your select query.

I have a GridView which with a CheckBox in a TemplateField.
When I check something and hit the submit button, the items that I have checked are not check on the postback.
I tried using EnableViewState and that did not help.
How can this be fixed?

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="SELECT">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server"/>
</ItemTemplate>

You need to override LoadViewState and SaveViewState methods to maintain the selection.

I am trying to upgrade an ASP.NET application to .NET 4, but one page on my site contains an exception:
Argument Exception: an entry with the same key already exists".
What is different about ASP.NET 4 that might cause this problem?
One Solution
Not sure why but setting clientIDMode="Predictable" rather than Static seems to have avoided this exception message.
I had the same issue and fixed it.
I went through my entire ASPX page and found ASP.NET control that had the same ID as another.
I also tested this fix, and found that any control that conflicts with another control on the page will cause this error.
<asp:Label ID="FailureText" runat="server" EnableViewState="False" ClientIDMode="Static" />
<asp:Label ID="FailureText" runat="server" EnableViewState="False" ClientIDMode="Static" />
It happens when you Copy/Paste elements on the same page.
This in your web.config may also cause the error by allowing duplicate IDs
<pages clientIDMode="Static">
I have this error too and not resolve with this
<pages clientIDMode="Static">
