Hi,

I need to be able to show / hide (toggle) all columns in a grid view where the columns name begins with (A). I've search and found this script:

function HideColumn(index)

{

var columnCount = RadGrid1.get_masterTableView().get_columns().length - 1;

if (index < 0 || index > columnCount)

{

alert("Invalid index! The valid range is: " + 0 + "-" + columnCount);

}

else

{

RadGrid1.get_masterTableView().hideColumn(index);

}

Does anybody have any suggestions how it could be tailored to accomplish my goals?

Control gets ajaxified without intent

Hello!

I have a user control that searches recursively for an radajaxmanger in its page hierarchy. Then the control adds its components that should be ajaxified like that:

ajaxManager.AjaxSettings.AddAjaxSetting(btnEditValues, gridPanel, radLoadingPanel);

the page hierarchy looks like that

Page (with the Ajax Manager)
-Control
--gridPanel
---btnEditValues

Now every control in the gridPanel makes an ajaxpostback as well.
When I try to exclude the control from the AjaxRequest with a javascript (OnRequestStart for example) the Clientside event "OnRequestStart" is not even called. But still an ajax postback is made.

I successfully excluded other controls from the postback, like "btnEditValues".

Is it possible that control that are the updated ones a somehow implicitly the updating ones as well ??

I'm really stuck here...

thx in advance for your help,

kind regards,
M

combo box with check box

I am trying to write a javascript code. This is code I have right now.

<script type='text/javascript'>

function onCheckBoxClickctl00_Content_ddc1_CB1(){

var combo=$find('ctl00_Content_ddc1_CB1');

var CountChecked=0;

var text='This is the text message';

var max ='4';

var items = combo.get_items();

for(var i=0;i<items.get_count();i++){

var item=items.getItem(i);

var chk1=$get(combo.get_id()+'_i'+i+'_chk1');

if(chk1.checked){

CountChecked ++;

if(max < CountChecked) {

chk1.checked = false;

}

text+=item.get_text()+',';

if(CountChecked > 3)

{ text = 'You have ' + CountChecked + ' items selected :';}

}

text=removeLastDelimiter(text);

if(text.length>0){combo.set_text(text);}else{combo.set_text('');}}

</script>

if(text.length>0){combo.set_text(text);}else{combo.set_text('');}}

I would like to write the text in the first line of the drop down. Something like items._array[0].set_text(text). But when I did this I get an error. Can you please tell me how to do this.

Thank you

Access Insert Template Server Side

I am working on a project that requires complex conditional validation and I want to be able to access the controls in the edit template on the server validate event. I have looked through the object model and I am not seeing anything I can use to access the page values. Any clues?

During an edit I can use the RadGrid1.EditItems but insert there are none there.

Expanding

Hi,

I have a radgrid control that has 3 nested gridtableview within it. I'd like to
have button on the client side that expands a particular gridtableview when
clicked. I would expect it to expand all the gridtableview (i.e. 1 per row of
parent grid).

Any suggestions as to how I can set this up?

Loading of user controls in Nested View Templates

Hi,

Plesae let us know how to achieve the following.

1. Avoid loading the user control in nested view template when outer grid/page loads.
2. Allow loading of user control ONLY for the expanded row of the outer grid.

Find below the source code to work on. Any prompt help on this is really appreciated.
Note: The source code really doesn't have any parent and child relation in the data that it displays because it just a sample.

Preventing RadProgressArea from Polling on Page Postback

I have a RadProgressArea on the page to track a specific operation. I find, however, when the page is posted back for an unrelated operation that it starts polling. How would you stop it from polling on all postbacks and focus just on the specific operation I want it to?

Custom filtering not working

For Custom filtering it is only working for "No filter" option. and for any other option e.g. "EqualTo" it is not even postbacking sometime.

I am attaching my sorted list (which is according to filter options) to grid.But it is still showing except "No filter".i.e. all over inconsistant behaviour is there.

I am using "ItemCommand" Event. and binding all data in "needDatasource" event.
