Javascript, Firefox 4.0.1, MasterTableView

We are currently using an older version of RadGrid (4.0.1.0) in our application and I have noticed that the javascript being used access the MasterTableView is no longer working in FF4.0.1. It was working fine in FF3.5

The script in question looks the same as your samples:

function ShowEditForm(id, rowIndex) {

var grid = window["<%= grd.ClientID %>"];

var rowControl = grid.MasterTableView.Rows[rowIndex].Control;

grid.MasterTableView.SelectRow(rowControl, true);

return ShowPopup("<%= GetUrl() %>" + id);

}

The same code works fine in IE8. In FF4, Firebug reports the variable 'grid' as Object { } and grid.MasterTableView is undefined. Under FF3.5, the variable 'grid' is listed as Object { Type="RadGrid" }

Any ideas how to fix this without upgrading the Rad controls?

Regards
Alan

Auto Generate Columns and Column Settings

I have a grid bound to a dynamic view. I am using the NeedDataSource and have the AutoGenerateColumns set to true because I never know what the column headers or count will be.

I have AllowFiltering set to true to allow users to work with the returned data. There are a couple of column settings I would like to apply to all columns and I am hoping to avoid writing a bunch of code in the PreRender event and then rebinding.

I would like to set the default filter (CurrentFilterFunction) to "StartsWith" and not "Contains" for all columns.
I would like to set the default FilterControlWidth to be the same width for all columns. I noticed that string columns are one size and numeric columns are another (larger?).

I've serched through the forums but can't find anything. If someone can provide a link or a suggestion that would be great.

Thanks,
Craig

Grid - EditFormType WebUserControl does not render the labels of the form

Hi,

I am having some issues when a grid is in edit/insert mode because the
web user control used to edit the data does not render properly. The labels
of the form are not displayed (They are invisible) and when you type something
in the text boxes the characters are not displayed.

One additional thing is that a pop window is opened and inside the popup window
a user control is rendering a grid. That grid opens a popup window when it is
in edit/insert mode. So, the escenario is a form, with a popup window that opens
another popup window.

The issue is happening only in Internet Explorer version 8. Now most of the users
of the company are using this version.

we tested the form with Internet Explorer 9, Google Chrome (Latest version) and Firefox (Latest version) and it works fine.

I attached two screenshots. One shows the problem, and the other one renders fine.
(I.E 9, Google Chrome, Firefox).

The easiest way to fix it is to upgrade the I.Explorer, but for now what should be the
best way to fix it momentarily.

Regards,

Leonardo Vega.

Selected row

Hey,

in a regular gridview I can easily get the number of the row which was selected.

dataGridView1.Rows[0].Selected = true;

somehow, I can't get it in a radGrid.

I tried:

string selectedValue = (RadGrid1.SelectedItems[0] as GridDataItem)["users"].Text;

but I keep getting excaption:
"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

Can anyone point out this code?

Thx

Tabstrip in editform template on radgrid

I have a radgrid with a template to edit a pretty big record.

I created the template, added a few fields, edited, saved all is well.

Next I added a tabstrip to the template, created tabs for billing address, mailing address, etc…

Everything looks great but when I try to update the record the information in the tabstrip does not get saved. (None of the tabs)

The few header fields outside of the tabstrip do update fine and no error is generated.

I hope this makes sense.

Thanks for any help.

Capture database value on insert

I use automatic insert, which calls an SQL stored procedure. This stored procedure checks if the newly inserted record already exists, if it does, it doesn't insert the record, and returns a NULL for one of the datafields. My question is, how do I capture the SQL result of this NULL datafield so I can display a message to the user?

ItemData bound is not firing while expanding the NestedViewTemplate

Hi there,
I have a grid in which there is a nestedViewTemplate that contains a radTab and each of this tab contains another Grid. While binding data to the main grid, all these subgrids are binding one by one for each row in the main grid which consumes more time to execute. Also if I expand one item in the main grid, the data is not binding in the subgrid and the itemDatabound is not firing. But once I change the page index, or sort, then the data is again binding. What I actually want is to stop the bulk binding of the sub grid and it should only bind once I expand the main row for each record. Below is my code for your reference

<telerik:RadGrid runat="server" ID="rdGdMain" ShowFooter="False"
