For this fallow the fallowing steps-

Enable the ASP.NET authentication for default website (in IIS) then create Desktop folder at C:\Windows\System32\config\systemprofile\Desktop.

step1 :  Go to run type dcomcnfg
Step2:   Click >Component services >Computes >My Computer>Dcom config> and select microsoft Excel Application>
Step3:   Right Click on Microsoft Excel Application>Properties>Security Tab
Step4-Under-Launch and activation permission->Customise->Edit->Add--type-(IIS_IUSRS)
-> ok -> Allow Permission-Local Lounch and Local Activation
Step5- Repeate Step4 for Under Access Permission

Reference--http://www.youtube.com/watch?v=ijfb3E_7t3o

IIS-Error Resolve--Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space. • To make more memory available, close workbooks or programs you no longer need. • To free disk space, delete files you no longer need from the disk you are saving to.

For this fallow the fallowing steps-
step1 :  Go to run type dcomcnfg
Step2:   Click >Component services >Computes >My Computer>Dcom config> and select micro soft Excel Application>

Asp.Net Validation Summary: How to show ValidationSummary using JavaScript

ValidationSummaryOnSubmit(); function exposed at client side.

<script type="text/javascript" language="javascript">

function PerformValidation() {
ValidatorValidate(document.getElementById('rfvName'));
ValidationSummaryOnSubmit();
}

</script>

Note: ValidationSummaryOnSubmit takes an argument as validationGroup. If you want to show ValidationSummary for a particular validation group, then call function passing name of validation group.

If function is called without any arguments, then it will show all ValidationSummary (if error) in page.
