I have a gridview connected to a sql database that allows the user to delete the record. I used the ASP.net automatic "options" for this. However, I would like when the user deletes a record, a message (textbox) appears in the form to say the record has been deleted.
View 5 RepliesHow do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?
Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"
I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

Im pretty new to ASP.net but am getting there slowly but surely! Its definitely growing on me.
The problem im looking at at the moment is i have a gridview displaying data from my SQL database, which works fine. I have enabled the selection option on the gridview which has placed a select link next to each row. Perfect.
What I am looking to do is be able to click the select button, and have the details from each column on that row go into variables when the page is posted back. I will then write these back to a different table in the database later on.
I see that when i click the link it is posting back the number of the row i have selected, but how do i use this to get the data from each column out of the gridview?
'm using a gridview with paging and sorting in asp.net (language = VB).The gridview shows all the artists in my database. I've added a searchbox above my gridview, so users can search for certain artists by name.The search option works. If I enter the name: John --> it shows the artists who have the name John.Now for the problem:If the user filtered the gridview (for eample searching for John) and switches to another page of the gridview, the gridview is again filled with all the artists instead of the artists that are named John.

I have grid view with different page index Based on the Page Number i have to enable different panel.
If page Index is 1 I have to enable Panel 4 If page Index is 5 I have to enable Panel 1 and Link Buttons like in such a way.
Dynamically needs to be updated based on the Grid View page number.
I have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.
