GridGroupingWeb Filtering when using Select Button

[krishna]

hi all,
iam using gridgroupingweb for filtering i have 7 columns.one column has select button. iam doing filtering in some of the columns.in the filtering all works except at Empty option in Dropdownlist of filtering.when i select all or particular thing it works. when i select empty in column also it works but after that it dos'nt. i mean if i pick empty and then all it does nt work. what ever i do after empty it does nt work. it is happening only when there is select button on one of the columns. if the select button is removed it works fine for everything.
i have taken select button in item template



forecolor="black" OnClick="Select_Click">


.

i think it is unable to instantiate again the select button after empty.

can any body solve it.

Hi Krishna,

In our control While working with Filtering, adding button to the template column in bound Field will result some unexcept behavior.so you need to add the button as template column in the unbound field.Let me explain in detail.

1)create a unbound field and add it to the visible column collections.
2)Add the button to unboundfield as template column in the QueryCellStyleInfo event.

This makes the Grid to instantiate the button once again, even if you select Empty option in the Filterbar


Take a look at the below sample.

Let us know if you need any other assist.

hi Gokul,
i tried this code as it is . but it is giving a runtime error as 'list.templateclass' does not implement interface member 'system.web.UI.ITemplate.Instantiatein (System.Web.UI.Control)'


thanks

Hi Krishna,

We have used 'Templates' in code to acheive this behavior and we added button programmatically using templates. Please look in the following KB, to know more details on using templates in code

http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=373

Also ensure that you have given the code of TemplateClass code correctly.

//The template class should implement the ITemplate interface.

public class TemplateClass : ITemplate
{
//see the attached sample's code for more details.
}

Hi Krishna,

For your notification, to change the GropDropArea's DataMember text, please have a look at the below code snippet.

//Renames the DataMember name
GridGroupingControl1.TableDescriptor.Name = "";

Either if you need to remove the GropDropArea, please look at the below code snippet.

GridGroupingControl1.ShowGroupDropArea = false;

thanks
krishna

[Gokul B]

Hi Krishna,

Kindly Let us know have you tried our sample.

* In our sample, we bind the GridGroup with AccessDatasourceControl.
* We created one unbound field named "Selection" and added the button as a Itemtemplate from Grid's QueryCellStyleInfo event. Before that you have to add the below code snippet in the Page_Init event.

Control c = new Control();
//Used to add templated controls in the Unbound field
TemplateClass mytemp = new TemplateClass(c);
//Adds the control container to the GridGrouping control Itemtemplate.
// since It is important to add the control to ItemTemplate when we add our own controls(i.e Button in your scenario) to GridGrouping Itemtemplate collection, Unless we can't handle the event inside the Itemtemplate.
GridGroupingControl1.TableDescriptor.Columns.FindByMappingName("Selection").ItemTemplate = mytemp;

* Then we handled the button click in the QueryCellStyleInfo event. While clicking on the button will gets the currently selected record(i.e CustomerID in my sample).

Let us know if you need more help.

hi ,
Filtering is not working Properly when i added the code snippet in Page init( the following code). when i select empty in the filter and then if i select any thing suppose "ALL" it is not instantiating anything..if i remove this code snippet in the page init filtering works properly but Button selct event is not firing.

code snippet

Control c = new Control();
//Used to add templated controls in the Unbound field
TemplateClass mytemp = new TemplateClass(c);
//Adds the control container to the GridGrouping control Itemtemplate.
// since It is important to add the control to ItemTemplate when we add our own controls(i.e Button in your scenario) to GridGrouping Itemtemplate collection, Unless we can't handle the event inside the Itemtemplate.
GridGroupingControl1.TableDescriptor.Columns.FindByMappingName("Selection").ItemTemplate = mytemp

can u respond quickly
thanks
