check radgrid row visibility at client

[Gilberto]

I'd like to check the row visibility of a radgrid's row at client.

I always get false in display variable in code below, even using masterTableView.get_dataItems()[i].style.display, then i get always none

obs: any rows could be hidden at client side.

var radGrid = $find('<%= RadGridFuncionalidades.ClientID %>');
                if (radGrid != null) {
                    var masterTableView = radGrid.get_masterTableView();
                    for (var i = 0; i < masterTableView.get_dataItems().length; i++) {
                        // debugger
                        var gridItemElement = masterTableView.get_dataItems()[i].get_element();
                        var display = masterTableView.get_dataItems()[i].get_display();

Any suggestions?

Hi Gilberto,

Could you please elaborate a bit more on the details. What is the way you hide the rows.
In order to progress in the resolution of this matter It will be best if you send us the problematic page, so we can replicate the issue.

Well i am hiding some rows at client, using method below, and when i check the row visibility i always get false/none as mentioned.

 var radGrid = $find('<%= RadGridFuncionalidades.ClientID %>');
                if (radGrid != null) {
                    var masterTableView = radGrid.get_masterTableView();
                    for (var i = 0; i < masterTableView.get_dataItems().length; i++) {
                        var gridItemElement = masterTableView.get_dataItems()[i].get_element();
                        var grid_id_modulo = gridItemElement.cells[1].innerText;
                        if (grid_id_modulo == id_modulo) {
                            masterTableView.showItem(i);
                        } else {
                            masterTableView.hideItem(i);

Thanks in advance

Thank you very much Pavlina.

Your answer was exactly what i was looking for.

My mistake was to use :

var display = masterTableView.get_dataItems()[i].get_display(); 

instead of:

var display = masterTableView.get_dataItems()[i].get_visible(); 

Thanks again

i was using build version 2008.2.1001.20 and then upgraded to build version 2008.3.1125.20. both build versions give me this result:

if i use the get_display() property, it always returns false.

if i use the get_visible() property, it always returns true.

i am using a simple example very near the one provided above. i am also showing and hiding rows using the method showItem(index) or hideItem(index).

all of this is within a user control and the javascript is wrapped in a RadScriptBlock. (I could not use a RadCodeBlock because when the OnGridCreated client event fired, it did not find the javascript function in the user control. The RadScriptBlock did). 

any hints?

Hi Johnathan,

Unfortunately the provided information is not enough to determine the exact source of the issue you are facing. At this point I will ask you to open a formal support ticket and send us a simple runnable application with reproduced this erroneous behavior. Thus I could do all my best to find a quick resolution of this problem.

it turns out that if i call "set_visible()" passing true/false as an argument to the method before calling "showItem()" or "hideItem()", the functionality works as expected when later verifying the row property "get_visible()".

[Pavlina]

Hello Johnathan,

What exactly do you mean by the functionality works as expected when later verifying the row property "get_visible()".
Could you please elaborate a bit more in the details.

Hi Arif,

In order to achieve the desired functionality I suggest that you handles on ItemDataBound event and get the needed textbox. After that check if the id is available and if so set the textbox as read only.
For more information about how to access the textbox, please refer to the following article:
