Hi, I needed to create some controls in itemdatabound(grid) coz the number of controls to be rendered was only known at item databound of grid. the controls needed to raise event so i added events at runtime. All was working fine until recently i was asked to have another view for those controls outside the grid. I managed to create the controls once again in pageload. but the treeview was having viewstate problems coz controls once loaded and then if changed , the viewstate for the previous controls was being assigned to current controls. I managed to solve this by disabling viewstate for all the controls but now i see that the checkbox checkedchanged event is raised only when it is checked. The reason being that on pageload , since the checkbox has no viewstate, so the default value being unchecked is considered changed only if checkbox is checked. The problem gets solved when i enable viewsate but i can't enable viewstate. Is there any work around for this issue... . can the viewstate be assigned values for a particular checkbox and then removed at a button click, because there is a save button and if i can clear viewstate values at click of that button then probably it would work. I have tried clearviewstate and its not working. Please provide help Thanks haseeb

Hello, I have some controls created at ItemDatabound. (created at itemdatabound because at item databound , i know which type of control to create). In these controls, i have a button which increases size according to its Text. i want to fix the size for all other controls based on size of this button but when i get the width of button, it gives me 0 pixels. Can anybody provide an idea on how to set the width for the rest of the controls. i have tried grid's pre render method but somehow i cant find any of the controls created in itemdatabound . Thanks Mark

Hi, I have an editformtemplate in a grid. The edit form contains 2 radiobuttons along with other controls. During itemdatabound , i convert the values of this column in grid to yes/no. Now on itemdatabound , when the form goes into edit mode i want to get the yes/no value and after converting to true/false want to populate radiobuttons. I am having problem retrieving the Cell data from the grid in edit mode.

Hi, i am trying to use a web control previously developed. The web control has been created a while ago and contains 4 -5 textboxes and an update button. The control validates all the data against specific regular expressions and displays a message if the data is invalid data otherwise stores in db. The control is working in 2-3 other pages. I want to re-use the same control but in a gridedittemplate. I can re-use the control and it seems to be working but the only problem is that if validation of data fails, the grid collapses (probably because it assumes that the function has completed. i want the grid to remain in expanded mode, until the value is saved... I am implementing my functionality as: in .ascx page (my parent page is a control too) , i have a grid with a template which defines the control as visible = false in itemcommand. i make the control visible , which works great but on update button of this child control i want the parent grid to remain expanded

hi, thanx for ur reply... if u mean to use something like this dim cs as scriptmanager = page.clientscript cs.RegisterClientScript(args) then this also doesn't work. otherwise can u please provide a sample code... Thanks ,

Hi, I have a tab strip (telerik), with 3 tabs. Each tab strip opens a separate Web Control. When i add javascript to first control's (pageload) on the first tab, the javascript works but when i add it in second or 3rd tab (user control page load),javascript doesnot render to page. (i cant see it in ViewSource) Please note that i cannot add javascript in the designer for page so am adding the script at runtime on page load. The javascript also works when added in Parent Page. It only doesnt work in 2nd,3rd tab controls. It starts working from 3rd tab when added on parent or first tab control. (and i am not allowed to add anything outside this 3rd tab control) My code for script is

dim script as string = " function Check(){alert('hello');}"
Page.ClientScript.RegisterClientScriptBlock(Me.GetType(),"mycustomScript",script,false)

Also i have tried RegisterStartupScript. The controls contains Ajax (RadControls) and script manager is added to parent page.The Manager Proxy is added to each page separately. Please provide help in this regard Best Regards haseeb

Thanks, i will try response.clearheaders . though havent tried it but i firmly believe that it should work Thanks again

Hi.. the response.clear erases html output but doesnot erase any headers. i need to clear whole page. according to MSDN The Clear method erases any buffered HTML output. However, the Clear method erases only the response body; it does not erase response headers. Can anybody provide some assistance on how to clear the header as well... Thanks Mark

Hi ,thanks.. It seems that i need to look into all config files... I will let you know if i am not able to solve the problem... Thanks Mark

Hmmm... , on my local machine i added the reference to dll (ie my dll) thru website->add reference, whereas on the server, i just placed my dll in bin folder because i thought that should be enuf. On my local machine, i didn't make any change to add service reference so i believe web.config should have not changed... Am not sure about settings file though... It seems that by adding reference thru website->add reference, asp.net on my local machine knows where to find the service reference files but when added to only bin, asp.net doesnot know whre to get service reference from ... Is there anyother way of adding reference on server? I have tried placing the files everywhere on server but it isn't working... I need to see the web.config file ... Thanks for replying

Hi, i have a windows services that uses a service reference to amazon web service. I have created a dll that actually has the service reference and the dll is called by my windows service. My windows service works fine. I also have a local asp.net application that uses the same dll and works great (Probably because dll and asp.net application are created on same machine). Recently, i moved the asp.net application to LAN Server. I copied the dll into bin folder. I also copied the service reference folder to bin folder and it turns out that the asp.net application is not using the service reference. It is calling my dll but the dll inturn isn't using the service reference. Can anybody please provide help on where should i copy the service reference folder or files. or wat approach i should take to solve this issue. I googled but it seems that i am not googling appropriate keywords. Any help, link etc will be highly appreciated Thanks Mark

thankyou

Hi Sashidhar , sorry for interruption.. It would be nice if u give me an insight to how u created these reports. What tool did u use? Thanx

Thanx alot

Hi, I have an asp.net application on the local server. I had to make some changes to the code so i copied the website to my personal system and made the changes. I had to include mysql ado.net connector, as some retrieval needed to be done from mysql database. I installed mysql ado.net connector on my pc but haven't installed it on the server. Because of this , the asp.net site when deployed to server throws an error of an unrecognized assembly. Though , the solution is to install ado.net connector on the server... but i want to know if there is another way in which i only copy the dll file and it works (as is the case with windows application where dlls reside in bin folder)... Thanx in advance

thanks for replying. I have used the autocomplete ajax extender but by multiple word search i meant how would i implement a search so that it allows "Battery for laptop aspire 234" or may be "Battery Aspire 234". Again by autocorrect i meant that if somebody happens to type in Apsire(instead of aspire) how would i suggest aspire ...

Thanks Abhishek, Your answers have always been a good help. Thanks again. I have another small question ... i searched for it but wasnt' able to find any good help. I am also trying to develop a multi word search which can perform autocorrect... Can u please provide an idea on how this is done or may be forward an article... Thankyou again
