RadGrid: Clear filter at client - side.

[Abhijit Shetty]

Hi Team,

I need to clear RadGrid at client - side.
I tried this: masterTableView.get_filterExpressions().clear(); which cleared array holding filterExpressions but my filter values were preserved in filter textbox!

Hello Abhijit,

Just use the following code:

function clearFilter()
{
    var grid = $find("<%= RadGrid1%>")
    var tableView = grid.get_masterTableView();
    tableView.getColumnByUniqueName("ProductID").set_filterFunction(0);
    tableView.get_filterExpressions().clear();

    var filterRow = $telerik.$(grid.get_element()).find(".rgFilterRow");

    //ProductID is the name of the column in my case; just substitute it with your own.
    var txtProductID = $telerik.findElement(filterRow[0], "ProductID")

    txtProductID.value = "";

    tableView.rebind();
}

Hope it helps.

Thanks Tsvetoslav,
After posting it in forum and doing some RND i found a link to modify FilterExpression at client - side as:
http://www.telerik.com/help/aspnet-ajax/grid-client-side-binding-adding-sort-filter-expressions.html
So according to you which is best and feasible option to do the same.

Hello Abhijit,

Well, do go with the help topic approach - it is more concise and uses an out-of-the-box api that I missed.


All the best, Tsvetoslav

Hello Telerik Team,

                              I need to clear Rad grid  filter without doing post back at client side, I was try masterTableView.get_filterExpressions().clear(); but it is not working, I was also try masterTableView.clearSort() but it do post back. I have to clear rad grid filter without post back. How can i do  this, please provide your answer.

Hi Abhijiit,

If you are binding the grid on the server, you can't circumvent the post-back - as it is needed to bring the new unfiltered data. If you are binding the grid client-side, just use:

masterTableView.get_filterExpressions().clear();
masterTableView.rebind()

Hope it helps.

Hello Telerik Team,

We have to set Current Page index of rad grid to 0 on client side only. We have tried with set_CurrentPageIndex on client side
for Rad Grid. but it was not working to set current page index giving an error.


We have to set current page index without doing post back.


Waiting for reply.



Thanks,

Hello Subodh,

To achieve the desired functionality you can try using the MasterTableView. set_currentPageIndex() function:

function resetPager()
{
      var masterTableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
      masterTableView.set_currentPageIndex(0, false);
}

Also I am sending you a simple example which demonstrates it. Please check it out and let me know if it helps you.

Hi Team, 

             Clear all Telerik:RadGrid filter column  not working at client side using following code. Is there any Radajax control effect to                clear filter column? because I use RadAjaxPanel in this page

             var masterTableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
             masterTableView.get_filterExpressions().clear();
             masterTableView.rebind();

 

Thanks & Regards

Hello Kishan,

The posted code snippet works, however you need to clear the filter controls' values manually. I am sending you a simple example which demonstrates this. Please check it out and let me know if it helps you.

Looking forward for your reply.
