Accessing cell values in datagrid
Posted: 28 Jul 10 5:18 AM

Hi All,
I have the following code executed on the RowCommand event of my datagrid just to see if i can access each of the values in the cells of the row i select (theyll be needed later):
The problem is i dont want all of the columns in the datagrid visible to the user and when i make one of the BoundField columns visible=false the ChosenValue.Text of the related cell comes out as "" (blank). If i then set it to visible=true i get the actual text value out as normal. WHYYYY?????
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = grdZACCOUNTPERSS.Rows[index];
TableCell chosenValue = selectedRow.Cells[0];
TableCell chosenValue2 = selectedRow.Cells[1];
TableCell chosenValue3 = selectedRow.Cells[2];
TableCell chosenValue4 = selectedRow.Cells[3];
TableCell chosenValue5 = selectedRow.Cells[4];
TableCell chosenValue6 = selectedRow.Cells[5];
TableCell chosenValue7 = selectedRow.Cells[6];
TableCell chosenValue8 = selectedRow.Cells[7];
string value = chosenValue.Text;
string value2 = chosenValue2.Text;
string value3 = chosenValue3.Text;
string value4 = chosenValue4.Text;
string value5 = chosenValue5.Text;
string value6 = chosenValue6.Text;
string value7 = chosenValue7.Text;
string value8 = chosenValue8.Text; |

Hi all, ive gotten past this problem now using the DataKeyNames value (the id). My next step is to populate session variables with the values to use when i open the next form but i get the rror: "The GridView 'grdZACCOUNTPERSS' fired event RowEditing which wasn't handled." Im new to the web development side of things but i thought all elements of the link button field click were done in the rowcommand event?
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = grdZACCOUNTPERSS.Rows[index];
TableCell chosenValue4 = selectedRow.Cells[3];
TableCell chosenValue5 = selectedRow.Cells[4];
TableCell chosenValue6 = selectedRow.Cells[5];
TableCell chosenValue7 = selectedRow.Cells[6];
string value2 = grdZACCOUNTPERSS.DataKeys[0].Value.ToString();
string value4 = chosenValue4.Text;
string value5 = chosenValue5.Text;
string value6 = chosenValue6.Text;
string value7 = chosenValue7.Text;
//put details into session variables for populating edit screen
Session["ACCOUNTPERSID"] = value2;
Session["ZPerson"] = value4;
Session["ZFamily"] = value5;
Session["ZClass"] = value6;
Session["ZStatus"] = value7;
open();
}
protected void open()
{
if (DialogService != null)
{
// DialogActionItem
DialogService.SetSpecs(300, 300, "EditAccountPersonsResponsible", string.Empty);
DialogService.EntityType = typeof(Sage.Entity.Interfaces.IAccount);
DialogService.ShowDialog();
}

Starting to feel a little strange talking to myself here.... 
Ive stopped the error coming up (called my CommandName "Select" instead of "Edit").
But my .ShowDialog line is not opening the form.......
I know it mjst have something to do with autopostback but im still not 100% on my web development behaviours. |
