Hi, I have a templated column with item template as imagebutton in each row and when i click button, it should fire the event on the page where i redirect to other page. My problem is that event is not fired when i click the button. I bind datagrid in the page load. If i bind grid in !IsPostback than it doesnt render the grid

Hi Mac 1. Take a look at the PortfolioGrid sample which includes a Hyperlink column. Also look at the How to create a Hyperlink Column in the Task Based Help section of the Essential Grid for ASP.NET Users Guide which should help you set up the ImageButton Column. 2. Refer to the Using GridGroupingControl section in the Introducing Essential Grouping Grid for ASP.NET: To data bind the Grid control users need to specify the appropriate DataSource and call DataBind() in the Web Form''s Page_Init() event. This is important as Init is the first step in the page''s life cycle and occurs when the page is initialized. Calling DataBind in Page_Load could result in unexpected behavior. Regards Arun

Arun, Thanks for the reply. I want to elobrate couple of points here 1. I tried hyperlink as in example and it works fine. 2. I tried image button, but the event hooked up to image button doesnt fire on postback. I tried that with putting my databind code in page_init. Though in ideal situation i wont be able to put the databind in init as the datagrid would be rendered in the button click event. The user will give search criteria and hit submit button which will render the datagrid. The datagrid will have a template column with imagebutton that will render based on the column value. Can you please post or send me an example with your grid component with image button. I will appreciate it. test // Code behined protected void NavigateToInsert(object sender, System.Web.UI.ImageClickEventArgs e) { Response.Redirect("~\\abc.aspx"); } >Hi Mac > >1.

Hi Mac, 1. Here is a sample that uses a Button in the template column. You can unzip it to the ../SyncfusionInstallDir/Web/Grid.Grouping.Web/Samples/1.1/Hierarchies/MasterDetailButtonSelect/CS/ folder or modify the .webinfo file and create an appropriate application directory in IIS and then try building and running it. It is deployed here. 2. Have you taken a look at the Alphabetical sample, which illustrates setting up Alphabetical-Paging logic using the grouping engine''s Summaries and Filters feature. You could use the Grouping Engine''s Filters to restrict the data being displayed in the Grid. Hope this points you in the right direction to do what you are seeking. If you are still having problems, kindly post a sample that we can unzip to Essential Grid samples folder and we will take a look. Regards Arun

Hi Toan,

As mentioned in our Users Guide, Essential Grid expects the data source to include a primary key column. Make sure to include a PrimaryKeyColumn to the TableDescriptor before calling DataBind(), as shown below.

Here is an example of how the WebPage's Init would typically look in an Application using the GridControl.


[C#]

private void Page_Init(object sender, System.EventArgs e)

{
//Add a primary key to the PrimaryKeyColumns collection

GridTableDescriptor mainTD = this.GridGroupingControl.TableDescriptor;

// CustomerID could be a field name in the datasource

mainTD.PrimaryKeyColumns.Add("CustomerID");

//Call DataBind

this.GridGroupingControl.DataBind();

}


Thanks,
A.Sivakumar
