In asp.net App I am using datagrid.Is there any event fired when a row is selected?I am not using any select button in grid.
what about : SelectedIndexChanged
"Occurs when a different item is
selected in a data listing control
between posts to the server"
SelectedIndexChanged event will fired when you click on Select Command.
You can use a CommandField or a templateField to implement a Select. if you are using a command field enable SelectCommand and assign somthing to Select Text. And if you are using a template filed put a LinkButton on it and Assign Select toCommand property like this
<asp:LinkButton ID="lnbSelect" runat="server" CommandName="Select" />
You can also use any link button with any command and subscribe to the RowCommand event.

I have a repeater control that has textboxes and buttons for delete/update. Also in my form I have the same looking row as the repeater but this is for new records that the user can fill out. One of the fields is required so I have a RequiredFieldValidator on it. However, because they are all in the same form (because this visually looks correct), I can't update one of the records in the repeater row because the RequiredFieldValidator in the add row won't be filled out, which is fine in this case because they want to alter a different record not add a record.
So how would I be able to use the RequiredFieldValidator to require this field but only when the Add button is clicked and to ignore it if the delete or update button inside the repeater control is pressed?
Set CausesValidation on your delete and update buttons to false.
<asp:Button ID="delete" runat="server" CausesValidation="false" Text="Delete" />
I have a hyperlink button in gridview with the attribute navigateurl = "".
<asp:HyperLink ID="btntest" runat="server" CommandName="Print"
CommandArgument='<%# Eval("rentalid") %>' NavigateUrl="" CssClass ="ImClass orangeButton"
Text="Display/Print Rental Agreement As PDF111" Target="_blank">
</asp:HyperLink>
I have a gridview command that makes a file and give this hyperlink button navigateurl attribute value but the problem is the hyperlink button is not calling gridview command because navigateurl is blank and also how can I render the hyperlink button when it got the navigateurl at the same time?
Use link button instead and do whatever stuff you want to do in command event of a linkbutton.
you can also style a linkbutton like a button.
I had a similar issue.... there are a few ways we came up with, but the best option for us was to use a literal in our grid-view. We set the html in the literal to open in a new window and passed the query strings that we needed. We did this twice, once selecting out the HTML in a stored proc. The other on a Row Data Bound. It sounds like either could work in your situation.
Hope this helps!
How can I format the gridview in asp.net on run time. Using the autoformat template?
For example, there is a gridview control, and there is dropdown list, inside the dropdownlist are the autoformat templates.
And I need to change the design of the gridview by just choosing from the dropdown list or is it even possible?
First of all, read carefuly GridView Examples for ASP.NET 2.0: Formatting the GridView. Then, on your dropdown list OnSelectedIndexChanged event, you can format which cell or column you want.
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
OnSelectedIndexChanged="DropDownList1_OnSelectedIndexChanged">
Accessing a DropDownList inside a GridView
I use below code in GridView for show each row information and when user click on this button(image) go to another page.
now i want to do it that when user right click on this button can open page in new tab
<asp:ButtonField ButtonType="Image" CommandName="Update" HeaderText="show" ImageUrl="~/Images/show.png" DataTextField="show" />
In place of button field use hyperlink field. OR, if you need CommandName, you can use TemplateColumn and use LinkButton control. That will solve your problem.
I have a dropdownlist and a textbox with a button on a form. When a button is clicked it does not go to my onclick even in the code but it goes to my dropdownlist's selectedIndexchanged event. How can I fix this?
I'm not a VB.net person but try changing your asp:button to this:
<asp:Button id="btnlookup" Height="24px" Text="LookUp" Width="60px"
OnClick="btnlookup_Click" runat="server"/>
Does your Page_Load have a call to changing the selected index or the items in the DropDownList outside of checking for postback?
Make sure the event handler is handling the correct control, or the button tag is referencing the correct method on it's onclick element.
If your dropdown list is not set to autopostback, and you change its value before clicking the button (and triggering a postback), then the dropdown's onchange event is supposed to fire.
...not that this explains why you click handler isn't firing.
