foreach (GridViewRow i in GridView1.Rows)
{
TextBox sname = i.FindControl("sname") as TextBox;
TextBox fname = i.FindControl("fname") as TextBox;
TextBox sex = i.FindControl("txtsex") as TextBox;
// Label lblpin1 = i.FindControl("lblpin") as Label;
TextBox tpin = i.FindControl("txtpin") as TextBox;
tpin.Enabled = true;
// lblpin1.Enabled = true;
string pinno;
pinno = Convert.ToString(tpin.Text.Trim());
conn2.Open();
SqlCommand cmd = new SqlCommand("update NRDetails2010 set SNAME='" + sname + "',FNAME='" + fname + "',SEX='" + sex + "' where pin='" + pinno.Trim() + "' and InstCode='" + Session["UId"] + "' and Sem='" + ddlsem.SelectedItem.Text + "' and scheme='"
+ ddlscheme.SelectedItem.Text.Trim() + "' ", conn2);
cmd.ExecuteNonQuery();
conn2.Close();
}

Unable to add update and delete functionality to any data control using MS Visual Web developer Express and SQL server 2008. The advanced options in the data connection wizard remain disabled. I can display data OK.

I'm having a HUGE problem with filtering!! I have a GridView1 with data from sql database (table called Requests) >> using asp:SqlDataSource Control.
and I have 2 columns (CV/ Transcript) which are Hyperlink columns..
I want to filter the data by:
1- GPA: for example view all data with GPA more than 3.55 and so on...
2- Credits: same as GPA (view all data with number of Credits more than 135 and so on...)
3- Dept. Name: it could be DropDownList and the user choose the department he wants to see results from.

View 1 Repliesi am still stumped with this operation: i am trying to retrieve a GridView selected row data..here is my code.. the commented part that gives me the selectedindex works just fine....but the one giving the selected row cell value does't work and there is no error.. The update operation is done successfully...weired. i need to assigned selected row cells values to variables ..do some calculations and then re-assign the result calculation to cell[9]..
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)

here below what i'm doing:
1. retrieving data using twitter APIs,
2. loading these data in a datatable using Linq to XML
3. binding the datatable in a gridview
twitter APIs includes URI images, and also strings that includes <a href> tags (i.e. hello world <a href="asp.net">asp.net</a> hi again)
the problem is that i'm not able to load these uri images in the gridview neither the hyperlinks instead i'm dipslaying the uri of the image and the tag itself
I need to export a gridview to excel and am having trouble with the layout. I found a number of good articles that explain the basic mechanics of the export. One simple approach that works is:
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
Response.Charset = ""
Response.ContentType = "application/vnd.xls"
Dim stringWrite As New System.IO.StringWriter()
Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
grdExcelExport.RenderControl(htmlWrite)
Response.Write(stringWrite.ToString())
Response.[End]()
My issue is that the gridview that appears on the screen with all of its added rows, hidden columns, and such does not show properly in Excel - the hidden columns from the header now show; there are missing data rows and so forth.
The RowDataBound event adds rows in the Header - these do not make it into Excel. The sql code does a GROUP BY WITH ROLLUP and the last total rows do not show in Excel, although the intermediate ones do. After my first DataBind of the table, I append 5 rows of special summary information which the RowDataBound processes correctly, but none of this goes to Excel.
So my wonderful Gridview on the screen becomes worthless in the transfer. How do I get my highly custom-formatted gridview into Excel??
i got checkbox in gridview under like tis. when i checked, it's able to retrieve the value from 3rd (c) column but,
i was unable to assign this value into another textbox (totalAmtTxt).

I have been searching the internet for a solution to this for hours. I have tried all of the following methods to set the column width on my GridView control:
1. <asp:TemplateField HeaderText="ColumnHeader" ItemStyle-Width="100px">
2. <ItemStyle Width="100px" Wrap="False" />
3. GridView.Columns[0].ItemStyle.Width = 100 both on the PageLoad event and, out of desperation, on the RowDataBound event.
I have tried these settings by themselves and in combination. I have also experimented with different CSS width settings for the GridView and its containing <div> (including none) to no avail. The GridView columns are always equally spaced and wrap the row description text in the first column in a rather ugly fashion. As this needs to be fixed for a presentation to a client on Monday, I would be eternally grateful to anyone who could point me in the right direction.
I have a gridview and I want to fix the column size to a certain size regardless of the length of the data in a given cell.
I have tried everythign I can think of from
gvwProjects.Columns[1].ItemStyle.Width
gvwProjects.Columns[1].ItemStyle.Wrap
to setting the length of the lblContol in the template but no matter what I do the column size automatically increases beyond my fixed size to meet the size of the longest cell in the bound datatable.
