View 1 Replies how i add DropDownList in edit mode of DataGridView by DataSet through code not visible?
As we know that by default Every Column in Edit mode is a TextBox I want to replace this to DropDownList through code.
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?
I am building a web page that will be presenting users two dataset results from two stored procedures in sql but the data is not similar. Is it possible to present both datasets to users in one datagridview? I am unable to do a union of the data in SQL due to the fact that the results aren't similar and wanted to see if I could work around this issue with .net.

View 1 RepliesI have a grid view with edit and save buttons when I click on edit it is letting me edit it and if I click on save it is lettingme save the data that I have edited.
The thing is after save is done it is showing the data in edit mode i.e <edit item template > mode I am still seeing the textboxes if I refresh the page then I am seeing it normally.
How can I stop the gridview to show edit mode after the save is done?
Can someone tell me if there is a technique to make an entire Column within an gridview (for example digits) editable (instaed of a single row) and update this column after changing values by press an Update-button?
A commercial solution is also o.k. with me, but, of course, a method to do it ourselve would be nice.
- I want to put multiple rows of a gridview into edit mode
- I have not found any easy method to accomplish this task. I found a way to programmatically put a gridview into edit mode, but in testing the code below it works for only 1 row at a time :

I have a page with 2 GridViews on it. The top GridView shows all the Bike Riders the bottom GridView shows all the Bike Lockers. I have set up both GridViews to be able to Edit the data. And the top GridView to Select.
When I click the Select buton on the top GridView I programically reset the DataSource for the bottom GridView to show the Locker for the Biker of the top GridView Selected.
So far everything works great. I select a Biker on the Top GridView and the Bottom GridView resets just showing one record for the bike locker.
The problem is that if I then click on the Edit button on the bottom GridView (The Bike Locker GridView) the GridView goes into the Edit Mode but it now shows all the Bike Locker records and the edit record is always the top record of the GrdView.

that say that the tables must be similar to be able to merge them into a single datagridview. I know that datagridviews only like one table at a time, but I was curious if anyone had found a way to merge two dissimilar tables to one datagridview or not.

View 7 RepliesTrying to update a .NET .20 datagridview in the following scenario. A page contains a formview. The formview contains a datagridview and some other fields not in the grid. The formview has its own ObjectDataSource and the datagridview has a separate ObjectDataSource. Each ObjectDataSource has an OnUpdating event. Clicking a Save button triggers the formview update event and the "non-grid" ObjectDataSource updates without a problem. In that same event, I also want to update the grid's ObjectDataSource. Because it's a grid, this OnUpdating event has to loop through each row, get the data for that row and set the UpdateParameter values. A foreach loop can get the values, but how do I trigger the update before looping to the next row?
Should I try calling a different kind of event for the DataGridView's ObjectDataSource? Or is there a way to get all the grid's new data at once as a dataset or datatable and do one bulk update? The datagridview does not have row-level edit/update buttons. It is meant to be an all-or-nothing kind of update.

HtmlTextWriter hw =
new HtmlTextWriter (sw);
GridView1.DataSource = RecordsDataSet;
GridView1.DataBind();
GridView1.AllowPaging = false ;
GridView1.DataBind();
GridView1.HeaderRow.Style.Add("background-color" ,
"#FFFFFF" );
for (int i = 0; i < GridView1.Rows.Count; i++)
{
GridViewRow row = GridView1.Rows[i];
//Change Color back to white
row.BackColor = System.Drawing.Color .White;
//Apply text style to each Row
row.Attributes.Add("class" ,
"textmode" );

I have calculated a value (say, Total) from datagrid values using RowDataBound event.
I want to show the value by adding a new column into Grid.
I need to add 3 rows to a footer, i did a total but dont know how to add 2 more,
I have a variable credits that i would like to display on the next line and then net the 2 on the 3rd line.
I have looked at properties of the e.Row and was thinking if i could add a table?? Is there a to table method of datagridview? That way i could add the rows?
protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Footer)
{
double totald = Convert.ToDouble(dt.Compute("Sum(Bal)", string.Empty).ToString());
e.Row.Cells[0].Text = "Total";
e.Row.Cells[0].Attributes.Add("align", "left");
e.Row.Cells[2].Text = string.Format("{0:n0}", totald);
e.Row.Cells[2].Attributes.Add("align", "center");
e.Row.
}
}
