protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm");
string frm = t1.Text;
TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub");
string sub = t2.Text;
string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')";
SqlCommand com = new SqlCommand(cmd,con);
int a = com.ExecuteNonQuery();

But the strings 'frm' and 'sub' returns null values.

Forms Data Controls :: Filling A GridView And Its PageIndexChanging

Feb 14, 2010

In a webform I have two textbox (txtDNI and txtAPE), 2 buttons (b1 and b2), 1 gridview (myGV) and 2 functions (dt1 and dt2) that return a DataTable txtDNI will be a parameter for dt1 function and txtAPE will be a parameter for dt2 function

DNI [_______] (b1)
APE [_______] (b2)
[ | | | | ]
[ | | | | ]
[ | | | | ]
[ | | | | ]
[ 1 2 3 4... ]

When I press b1 myGV will be fill with the dt1 function's datatable and when I press b2 myGV will be fill with the dt2 function's datatable myGV allows paging=true and when I press the next index (2 or other) It appears a PageIndexChanging error. So the pagination isn't automatic and I have to code the PageIndexChanging event When I use a ObjectDataSource and I connect it with myGV the PageIndexChanging error dessapears and the pagination is automatic The problem is the ODS only have a one selectfunction (dt1 or dt2) but not both and the configuration is on design time

The same happen with the PageIndexChanging event where I fill myGV again (with dt1 or dt2) and set the new index (myGV.PageIndex = e.NewPageIndex) and What is the problem?? ... the problem is, for example, when the user erase txtDNI and change index of pagination ... the PageIndexChanging event is fired and call the dt1 function but the txtDNI(parameter) is empty and occurs an error, the function returns an empty datatable and myGV is empty too for avoid this I create viewstates variables for each function, so I have a 2 viewstates and fill them when the user press b1 or b2 When user press the pagination, the PageIndexChanging event catch the viewstate variable and convert it into a datatable and the problem of the automatic pagination is controled The problem is I don't have 1GV in the webForm I have 5GV in some pages... and I try to avoid...

1. all the code in the PageIndexChanging events of each GV in the webform.
2. use the viewstate variables

Forms Data Controls :: PageIndexChanging And Other Events Of Gridview Is Not Working

Jun 3, 2010

I am working on object data source and datagridview. I have given object data source to the grid view as the data source of grid. The issue which i m facing is that whenever i click on next page(like 2 or 3 or 1) it takes lot of time to fire. although it is fired but I have to wait a minute or two and then it fired.

Whenever I click any event(e.g. next page , page 5 ,3 or edit etc) of gridview it does not give response. If I wait for a minute then click one of event then it performs, and then again I have to wait to fire other event.

Forms Data Controls :: Commandargument Wouldn't Change For Session As Long As I Didn't Refresh The Gridview?

Jan 29, 2010

I have a gridview set up as follows:


Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:

[Code].... far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:

* I go to the page and look at the gridview

* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)

* I click select.

What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).

I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..

Forms Data Controls :: Way To Get Gridview Name From RowCommand GridViewCommandEventArgs

Forms Data Controls :: RowCommand Not Firing Inside A Gridview ?

Sep 2, 2010

I'm trying to fire the RowCommand event on a DataGrid control. I've previously done that, but not in this precise case.

Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary.

The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.

Basically I have a GridView which I bind to a DataSet. According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).

By pushing this button, I want to show a second GridView containing those details.

Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.

The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')". When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!

In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.


And the code of my .aspx :

Forms Data Controls :: Exception With GridView RowCommand (Cancel)?

Mar 12, 2010

It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).

Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:

"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
