I got a function to load a grid view and works fine. Then, I got a button, when click, I wanted to add a new row into the grid, what I did is I add a new to to the dataset and rebind the dataset to the grid view.
The problem I faced is that is it able to add a new row, but it only shows ONE column only, which is the most left column.

im now created a function where i can import excel file to be displayed in gridview and then insert the data from gridview into database.

How to fire a button click event inside a grid view.
View 2 RepliesI have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.

I have a GridView within an UpdatePanel - <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true">
Without listing any Triggers, I get a full postback when I visit a particular row within the GridView and click the 'Edit' button for that row.
However, if I enter the following trigger...
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
Is there a way to access the updated text property of a TextBox which is inside a GridView cell when a Wizard controls next or previous buttons are clicked? I have a requirement to not use the edit and/or update buttons on the GridView row. Therefore, I am trying to figure out a way of grabbing the updated values of each TextBox of the GridView on the PostBack. Furthermore, these controls (i.e. Wizard and GridView) are within an AJAX UserControl.
