View 2 RepliesIs anyone able to offer any decent alternatives to the telerik ASP.Net controls.
I'm in the market for a decent grid control with all singing all dancing extensions... bt I'm finding the telerik grid really hard work to deal with.
The telerik controls do look good, but after a day of hard work with them I'm just looking to see if there are any other 3rd party offerings?
give me any pointers for free tutorial on RADGRID or give me a simple example on how to create a RADGRID and bind it to data source.
View 2 RepliesI've tried to find the answer, but am not having any luck and am wasting to much time trying to figure it out. Using RadGrid from Telerik, latest version of their Ajax Controls, I've added a Select to each row, and can't figure out how to get the value of the selected row. Prefer to get the value of the ID column (from ID field in my database) or other specific columns. C# or VB example will work, VB preferred.

I have a RadGrid with filtering. I set AutoPostBackOnFilter="true" and CurrentFilterFunction="Contains" on my columns. Ok it works fine, user don't have to open drop-down list to select type of filter. But now, I want to hide filter buttons.
I need to collect additional information from the user when they initiate a delete on a radgrid. Right now I am presenting the user with a confirmation dialog box that lets them click "OK" to continue but I need to add an additional textbox to collect a reason.

I want to limit the number of characters that can be entered in the textbox. How do I set the MaxLength of those textboxes
View 1 RepliesI have a checkbox column in a RadGrid that I want the user to be able to check/uncheck it and set the attached property. When the grid renders however, the checkboxes are disabled, because the grid is not in "edit mode". All the examples I'm finding want me to go through a lengthy process of selecting the record, putting it into edit mode, changing the value, saving the value.... yada yada yada...I just want the whole grid to be in edit mode (or the column, or whatever works) from the get-go, so the end user can make a one-click change to the data value. I know there must be a way to do this, I just can't seem to find it.
View 1 RepliesI have a page with a drop-down. Based on the selection in the drop-down, data gets loaded and populates a RadGrid. I am using a custom user control for the EditTemplate, so I can't use radGrid.DataBind(). Instead, I have to use radGrid.MasterTableView.Rebind() in association with a NeedDataSource event handler.
My problem is that when I load the page initially, I populate the drop-down and automatically select a value (first item in the list) which triggers the databinding on the RadGrid. I can step through the code in debug mode and see that the grid is being populated with data, but when the page displays, it doesn't get rendered. When I then manually choose an item from the drop-down, which triggers the same grid databinding code, it displays properly the second time.
How do I get it to display the grid the first time the page loads?
I'm getting a blank column when switching to another page using the default pager in the telerik radgrid. As data for each row, it shows the type of data i am using for the rows (SearchRecord)
Anyone have any clues as to why this may be happening? It doesn't show up on initial population of the grid, but only when I do paging. My columns are built dynamically but i confirmed that when my columns are built, they are the correct number.
When handling the OnUpdateCommand event on a RadGrid the DataItem is null.
I thought that this would also represent the data item being represented by the row.
The Radgrid is populated from an IList and in the handler the code looks like this...
protected void rgAllocatedClients_UpdateCommand(object sender, GridCommandEventArgs e)
{
if (e.Item is GridDataItem)
{
var gridDataItem = e.Item as GridDataItem;
var client= gridDataItem .DataItem as Client;
This works find when handling the ItemDataBound event but not when handling the UpdateCommand event. I really need this as in my Client class is the Id of the row I want to handle the update for.
I've got a DNN application using Telerik RadGrid. We're exporting some data from the Grid but when we drill down on the grid control and export the data we only see the initial top level data, never the updated Grid. Here's my table tag and supporting code. I'm not an expert in ASPX/C#so please forgive my newbie-ness.
<mastertableview autogeneratecolumns="False" datakeynames="AccountId" datasourceid="SqlDataSource1"

how to find html anchor control in telerik:radgrid ?
View 1 RepliesI wanted to ask what is the best practice to manage width of the radGrid.
For my application most users are running 1280 x 1024 so I would be happy to set my overall grid width to 1100. However, depending on the form in use, I sometimes have horizantal scroll bars. To solve this, I have been playing with the width of the grid, and also I have played with setting the itemstyle-width for one or two columns. Sometimes I accidentally get it right, and sometimes it is not quite right.
What is the best way to manage this? Do I set the grid, and then all columns, or just the grid, or just the columns? I guess there is a best practice, so just wondering how you handle it,
Using VS2008, and Telerik radGrid version 2010.1.519.35
I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy.
IOW, I need to change the culture of the form to en-GB culture.
In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format.
I am not sure whether I need to set this at web.config level, page level or at the column within the control.
I was creating another usercontrol with Telerik's RadGrid and Calendar.
[code].....
The problems are, (1) when I click the submit button. the data in the RadGrid is not changed. (2) how can we check if there is nothing selected in the Calendar controls, because there is a date (01/01/0001) set even if we do not select anything from that calendar, thus Calendar1.SelectedDate != null is not enough.
Is it possible to Call C# code from a Telerik radconfirm? I can make it call Javascript, but no server side code. I want the user to click a button which gives them a popupbox (radconfirm). With the radconfirm - if the user selects "yes" the c# code will be executed, if they click "cancel" no code will be executed
<asp:Button
ID="button1"
runat="server"
CssClass="resetOk"
Text="OK"
OnClientClick="radconfirm('<h3 style='color: #333399;'>
Are you sure you want to reset this budget?</h3>',confirmCallBackFn,
330, 100,null,'Confirm Reset'); return false;"
/>
foreach (Control control in ContentPlaceHolder1.Controls)
{
if(typeof(Control).Equals(Telerik.Web.UI.RadEditor))
{
label1.Visible = true; label1.Text = "dhchk";
// control.CssFiles.Add("~/styles/myStyle.css");
}
}
Error;-
'Telerik.Web.UI.RadEditor' is a 'type', which is not valid in the given context
Also, is this the correct way to add CSS class to radEditor controls ??
control.CssFiles.Add("~/styles/myStyle.css");
I actually wanna add 3-4 customized classes..how to do that?
also I was wondering if I can add some javascript or something in my Master page that will detect the ALL the radEditor controls and set their css classes ? don't know much of Javascript..how can that be made possible? how do I go about that? but first I want css classes to be set in code behind..what's wrong with the code?
[EDIT]
@Geek..I tried calling like this..is it correct?
Control c = new Control();
DoSomething(c);
now its giving this error in the method:-
The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)
[EDIT]
I do have this namespace added "using System.Web.UI.WebControls;" why this error ??
I am currently using Visual Studio 2008 to develop a hierarchical grid that displays records, its got 3 levels. The code looks roughly like this.
<telerik:RadMultiPage runat="server" ID="RadMultiPage1" SelectedIndex="0" RenderSelectedPageOnly="false">
<telerik:RadPageView ID="RadPageView1" runat="server">
<telerik:RadGrid ID="radGrd1">
<MasterTableView>
[Code]....
I have ommited all the code and just provided the skeleton.
The problem i am having is that when i add the Radgrid, the intellisense does not seem to pick it up and visual studio does not add it to the designer class either.
I have tried viewing it in design view and forcing it to sync and even manually added it to the designer class myself. These solutions have not solved my problem as although the intellisense does pick up the control after adding it manually, the control itself is set to null during run time.
So basically is it possible to add a rad grid in the first place and if so what am i doing wrong.
I'm using the Telerik rad grid and I'm allow the user to enter data directly to the grid.
I am using the "EditForms" edit mode and I also allow inserts using the same.
If the user edits a row, then I don't want to allow any other edits or inserts until the current one is complete or cancelled.
I am currently highlighting a row in a radgrid using OnMouseOver. I would like to know if it is possible to use OnMouseOver to select the row rather than highlight it.
Alternatively, I would like the highlighted row to remain highlighted if the radgrid loses focus, such as when a confirmation box pops up.
I created a RadGrid with a couple of fields for filtering and I can't seem to get the filtering to work. I can see it clearly posting back (the ajax spinny circle thing) after typing something in the filter box, however my results are always the same. I am using the following definition in the aspx file:
<telerik:RadGrid PageSize="4" ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" OnNeedDataSource="RadGrid1_NeedDataSource"
OnSelectedIndexChanged="RadGrid1_SelectedIndexChanged" Skin="Black" ShowFooter="True"
ShowStatusBar="True" AllowFilteringByColumn="True"
[Code]....
When I am trying to display data using radgrid I am getting error like "Index was out of range. Must be non-negative and less than the size of the collection. Parameter: Index".
Here is my code
[Code]....
All I want to do, is to get a values from a grid when it is not in edit mode. Note that I'm able to get two of the values (both the int32 fields), but I cannot get a reference to the "IsActive" Checkbox or the string "Delimiter" field.
let me know how I can accomplish this. Below is my code-behind. Notice the boldfaced fields I can't get...
