I am not sure why but won't vb.net compile and then cause the runtime error versus C# which would not even compile? I declared and initialized above the loops now and now I am getting a runtime error on the next line:
**e_link.ForeColor = System.Drawing.Color.Black
Someone told me a linkbutton causes a postback and there are a lot of them on this table so a hyperlink only causes a page refresh which is better in this case.
How can I hold the ID value from the first set of loops into the second?
This is the first thing I have ever made with asp.net and vb.net for that matter.

Those things are the same in your case. A typical hyperlink should send you to a new page, but you're detecting that it was clicked and handling it server side, which means the form is being submitted.

Where you do this:
e_link.ID = "Row=" & i.ToString & "Column=" & k.ToString
You are creating the ID. Simply copy the code you use to create that ID into the second loop:
e_link = CType(FindControl("Row=" & i.ToString & "Column=" & k.ToString), HyperLink)

Ok I did that but I am still getting this error:
Object reference not set to an instance of an object.
It is highlighting this line:
Line 151: e_link.ForeColor = System.Drawing.Color.Black
I have no idea what is going on excpet I think it is not recognizing the hyperlink located in that cell.

Well, the way you're doing this is going to be difficult. The page might not recognize the control yet enough to find it for you. So you might try going to the table itself:
e_link = CType(MyTable.Rows(i).Cells(k).Controls(0), HyperLink)

Honestly, I still think you're making this too difficult. You're chaning the IDs of HyperLinks to overcome the fact they don't have a CommandArgument like LinkButton. Where LinkButton produces the same results and is much easier to use in this case.

or you can invalidate pages in history.
in .NET 2.0 it is done by this line of code:
Response.Cache.SetCacheability(HttpCacheability.NoCache);

According to what i understood,this is how u can implement
foreach (DataGridItem dg in this.dgApproval.Items)
{
int i = 0;
//u use a for loop like this to find the template column of checkbox in data grid
if(((CheckBox)(dg.FindControl("CheckBox1"))).Checked == true)
{
//here i am retreiving the second column of datagrid as i neeeded it
//first column in data grid is the 0th column
string build_desc1=dg.Cells[1].Text.ToString();
//do what u want here... like i have written update query here
string query;
string query2;
query = "update build_master set approval_flag ="+ i +" where build_desc = '"+ build_desc1+"' ";
}
//make sure you bind the grid again to reflect the changes
BindGrid();
}
Happy Programming

Hello,
I posted something similar to this post before but this is slightly different.
The GridView gets populated and in the _RowDataBound event the Accept button(select CommandField button) gets replaced by a text value if there is one as shown below:
The find button populated the GridView correctly and Accept button is replaced with a text where necessary but not sure why when the checkbox on the page is clicked on, then ALL the Accept buttons are shown on the GridView (Which is incorrect).
The check box control only shows a label.
Thanks
If (e.Row.RowType = DataControlRowType.DataRow) Then
'show the clinic code since there is a start date other wise just show the Accept button...
'If Not (e.Row.DataItem("c_start_date").ToString() Is Nothing) Then
If Not (e.Row.DataItem("c_start_date").ToString() = "") Then
e.Row.Cells(9).Text = e.Row.DataItem("c_clinic_code").ToString() 'Change ur text here
End If
End If

That's because you do it in the RowDataBound event handler which basically happens when data is bound to the control. On postback, this method does not execute if you don't bind data, and the button reappear. So like I said in the other post, you should use two controls here and simple use the Visible property to control the visibility of the controls as this property is persisted in the ViewState.

Hi Developers
I have written code for two way sorting of Datagrid, and its working fine, BUT I want to have two "Arrows"(Upward and Downward) in each column of datagrid. So that when I click on upward arrow grid is sort in Descending and when I click downward arrow grid should be sorted in Ascending Order.
Any code or reference related to this will solve my problem.
Thanks in advance
Lets work it Out.........!

Sure! But it would be highly appreciated if you could specify what exactly do you want to know.
Otherwise read http://msdn2.microsoft.com/en-us/system.web.ui.datasourcecontrol.aspx
or any other page from 17,800 pages which google spits on you when you type "DataSourceControl" in.
