01-17-2007, 8:50 AndrewC Joined on 01-11-2007 Posts 23 Accessing Tab text from tab page Hopefully this will be my last question... ;-) I need some way to change the text of a tab based on the .rowcount of an ASP.NET GridView control on that tab page. Basically, I need to add the rowcount to the end of the Tab's text. Is it possible to access the .text property of a Tab in server-side code? Failing that, is it possible to add client-side script to the main page which hosts the tab, that would retrieve a value from a hidden field and add that value to the end of the text of that tab? I have tried a few ways to accomplish this, but I can't seem to get it to work completely. I was able to change the tab text in client-side code, but couldn't access either the GridView .Count or the value of the hidden field I put the GridView .Count into. I even tried using Page.RegisterStartupScript, but that seems to place its script code ahead of the PinTab's startup script, and so I was unable to access the value of the tab's text. The sooner you can get back to me on this the better, as this is holding up a project for a client... Thanks, -Andrew    Report

Just add a hidden input field to your page and set during page_load. Accessing tab item text should be possible with // access hidden field var value = document.getElementById("hiddenValue").value; // change tab item text for item 1 var item = __objPinTab1.getTabItemByIndex(1); item.setText(item.text + value); Regards, Hans-Peter    Report

01-18-2007, 6:07 AndrewC Joined on 01-11-2007 Posts 23 Re: Accessing Tab text from tab page OK, I tried that, placing the above code into the tab page, in a function, and calling it from the page's onLoad() event. I got an error: "__objPinTab1 is undefined." ?? I should mention that the main page, which has the PinTab control on it, is derived from an ASP.NET 2.0 MasterPage. I did try the following variations on _objPinTab1, one of which usually works with other controls when using MasterPages: __objctl00_ContentPlaceHolder1_PinTab1 ctl00_ContentPlaceHolder1__objPinTab1 and I got the same error. I tried looking through the page's source for the actual name of the object, but had no luck - all I saw was __objctl00_ContentPlaceHolder1_PinTab1, which didn't work, as I said above. Was I supposed to place the code you gave me on the page that hosts the PinTab control? If so, how would I get the value of the Hidden Field from the tab page ? BTW, I also re-created the page that hosted the PinTab control as a normal ASP.NET page, without the MasterPage; I get the same error about __objPinTab1 being undefined. So it appears the problem is not related to the master page... Thanks, -Andrew    Report

The name of the tab control at client side is created by __obj + "". If your tab controls name is myTab then the name is __objmyTab. My understanding was that the hidden field is on the main page. Is that wrong ? So, where is this hidden field ? Regards, Hans-Peter    Report

The page that hosts the Tab control I will refer to as "the main page". The actual name of the Pintab control on the main page is "PinTab1". The page with the GridView is on Tab #7, and that is where the hidden field is. I will refer to this page as "the tab page". So, again, the hidden field is on the Tab page, as is the gridview. In the code-behind (server-side) code, I have access to the number of items in the grid-view. I would like to add that number to the end of the name of the tab. So: I can get the number of gridview items into a hidden field on the tab page. I need, presumably in client-side JavaScript, to get that text from the hidden field and concatenate it with the text on the tabname. It all comes down to this: I need to write to the name of a tab, from within the page on that tab. I hope that makes it clearer... Thank you, -Andrew    Report

If you are inside a tab item page you can use parent.objTab to get access to the internal pinTab object. This should work: // get the number from a hidden value var value = document.getElementById("hiddenValue").value; // change tab item text for item 1 var item = parent.objTab.getTabItemByIndex(1); item.setText(item.text + value); Regards, Hans-Peter    Report

I know I have a reference to the correct tab item because I see its .text value in the Microsoft Script Debugger. Then, I get an error: "object doesn't support this method." And, from looking in the debugger, there does not appear to be a .setText method on the tab item. Furthermore, I don't see that method in your documentation either. Do I have an older version of the control? ?? I tried this: item.text = item.text + value; It doesn't give me an error, but it also doesn't change the text. I tried putting a .refresh() after the above line, too. Any other ideas on how I can get this to work? If it can't be done, it may prevent my purchasing the control. Thanks again, -Andrew    Report

01-24-2007, 12:04 AndrewC Joined on 01-11-2007 Posts 23 Re: Accessing Tab text from tab page OK, I downloaded the fix, and it stopped the error in I.E. Unfortunately, the following line: item.setText(item.text + value); gives me the text "undefined" with whatever the value in the "value" variable is. So I worked around that by using the following line: item.setText("Inventory(" + value + ")"; instead, since I know the Tab will always contain the beginning text "Inventory". This worked in I.E., but now I get an error in FireFox on this line: item.setText("Inventory(" + value + ")"; The error is: "item.setText is not a function." Any ideas on how to fix this? Opera and I.E. do not report an error, only FireFox. Thanks for your patience. I am impressed with the level of your support, and as soon as these last issues are ironed out, I will be purchasing the control. -Andrew    Report

I believe the problem was FireFox's cache, as you said. I thought you would like to know I have since purchased the Tab control. I do have another question, but I will start a new thread for that, as this one is getting long. Thanks again for all your help, -Andrew    Report
