Getting column data from GridView on page using MasterPage
-
Hi, Im having problems getting the value from a column in my GridView. I Have tried all of the following methods and a few others but none return the value and most just give Object not found errors.
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e) {//test message ShowMessageBox("CHANGING"); //Label temp=null; //temp.Text = (GridView1.FindControl(Label1.Text)).ToString(); //Label11.Text = GridView1.FindControl(Label1.Text).ToString(); //Label11.Text = GridView1.SelectedDataKey.Value.ToString(); //Label11.Text = GridView1.UniqueID.ToString(); //Label11.Text = GridView1.SelectedDataKey.Values.ToString(); //Label11.Text=GridView1.DataKeys.ToString(); //Label11.Text=GridView1.SelectedRow.Cells[0].Text; }Any help would be great. Im wondering if the problem is anything to do with the fact im using a masterpage for the template of the actual page im working on???? Or is it coz im not doing it the corect way for ASP.Net 2.0 ???? Thank -

Hi SHOWMESSAGEBOX is a method for displaying a pop-up. I use it just to confirm the action of the button click has occurred. This has nothing to do with the error / problem im getting.

ThankSorry 'bout the earlier smartie-pants comment ;) Do this: create a control at runtime to match your Gridview's templated control Label lbl = GridView1.FindControl(Label1); _yourVariable = lbl.text; Also I would imagine you gotta do this for the Label1 control appearing on EACH row... do you know how to do that?

Nila, dont worry i didnt take the comment as bad. Let me re-iterate what im trying to do, just to clarify we are thinking along the same lines. Ok, i have a gridview displaying data, when i click the select button on a given row i need to get the value of the data (unique_id) displayed in the first column. This column is also the DataKey for the gridview. So how can i get this info? Ive tried all sorts but to no avail. What would you suggest and how would you implement it? Sorry if this seems like im asking you to tell me how to do it all, but ive tried that many ways that should work and dont, that i really would appreciate it if you could explain in as much detail as possible. I dont know if this makes any difference but i am using MasterPage for the template of the page. I read somewhere that you have to drill right down to the control if using MasterPages. Is this true, and does it apply in this instance? If what you said above is still true
Label lbl = GridView1.FindControl(Label1); _yourVariable = lbl.text;Then how would you implement this? At present ive tried both SelectedIndexChanged / SelectedIndexChanging, but without success. I get the error that the Object Referenced does not exist. This happenes no matter if i try indexing the column or the Label1 control used to display the info in the required column. So again, id be really greatful if you could tell me how you would approach it, in all its horrible detail :zzz::->:omg: Thanks!!!!!!! -

THEN you can access them like this: String _city; ... protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { ... Label city = (Label)(GridView1.SelectedRow.FindControl("cityLabel")); _city = city.Text; city.Dispose(); //yup, always clean up! TextBox copy = (TextBox)(GridView1.SelectedRow.FindControl("copyTextBox")); copy.Text = _city copy.Dispose(); } Give this a try. Let me know if it works ro not :-)

Mate I Loves Ya! That works perfectly!!! Thanks a lot. But perhaps you can tell me 1 thing? Why does it only work when passing the Controls Data to a variable and then onto the static label control, yet it doesnt work when i miss out the middle man and try getting the data from the dynamic label and adding it straight to the static label? Thanks again. I appreciate your time!

Oh I have no idea why... typically when something doesn't work, I find a work around and move-on. Im sure the 'corky' .Net has its reasons, I just don't have time/patience to figure out the WHY ;-) Now, what does Mate I Loves Ya! mean??
