I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code

View 20 RepliesI have the below label. I need it to be a link that will cause the following:
Existing label INSIDE a DataList Item Template;
<asp:Label ID="Label10" runat="server" Text='<%# Eval("CG_ID") %>' Font-Size="X-Small"></asp:Label>
I need to change this label to a link that will cause C# code behind to:
tbxCG_ID.Text = Eval("CG_ID")
and then call this:
protected void ListBox1_SelectedValueChanged(object sender, EventArgs e)
I keep creating a DataList1_SelectedIndex_Changed event created when I double click the label or a link button. What is the code needed? I can see the Eval("CG_ID") value with the label but I don't know how to get it into tbxCG_ID.Text and fire the ListBox1 event.

View 2 RepliesI have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?

I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.

Get Gridview item template textbox value to string variable?
I have a Formview residing inside am Item Template of a Gridview. The formview is not populating, and I am pretty convinced that I am not passing the parameter properly from the Gridview to the Formview. I have listed the relevant code only, so that you can scan though it easierGridview tag:

not quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:
[code]....
But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.
I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID
CustomerID
InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.

But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there.
