How to hide a row in gridview while clicking link button?

Question

0.00/5 (No votes)

See more:

if (e.CommandName == "Delete")
{
int index = Convert.ToInt32(e.CommandArgument);
GridView1.Rows[index].Visible = false;
}

I wrote this.But it's showing "Input string was not in a correct format." instead of storing row position to index.

Can you tell more?
like an example of the link button you talk about?

Edit:
With this i mean what commandName / commandParameter and so on did you give the link button

<asp:LinkButton ID="LinkButton1" CommandName="Delete" runat="server" Text="Delete" />

This the link button. While clicking this corresponding record should lose the visibility

You use e.CommandArgument.
but you don't set an argument in your linkbutton

Solution 2

There are 2 possible reason for the error :-

1. In The Below Code check if e.CommandArgument returns Integer

int index = Convert.ToInt32(e.CommandArgument);

2. Check if the index supplied is not less than 0 or not negative

GridView1.Rows[index].Visible = false;

Solution 1

first check whether you are getting e.CommandArgument an integer or not.
one more thing is for deleting a row, use GridView1.DeleteRow(index);

I Think OP wants to hide the row, not to delete.

Member 10675393 15-Apr-14 2:55am

Yes of course. Record should not be deleted. It should Hiden

I clearly mentioned that if he wants to delete it, he can use DeleteRow method...
