Hi,
I have a menu control in which i use a dropdownlist and i use the control in all the pages .The data is bound dynamically at runtime .But it so happens in some pages the item names in the dropdownlist occupy more space than the width of the ddl hence not visible completely .I cannot increase its size in the menu control.Is there a way to View the complete name on selecting the dropdownlist control .
Pls help me out,
Thanks in advance.

I am not sure if this is the best solution but just try it.
Use javascript to display the name on mouse over,steps are as follows
1.try to add a div tag in html file:
<div id="tooltip" style="POSITION: absolute;" noWrap></div>
2.add this in code behind - ddl is name of your drop down list
ddl.Attributes.Add("onmouseover", "showTooltip();");
ddl.Attributes.Add("onmouseout", "showTooltip();");
i.e on mouseover you can see the name on mouse out the name disappears
3.Add the following javascript function
showTooltip = function ()
{
var obj = document.getElementById("ddl");
if(event.type == "mouseout")
{
document.getElementById("tooltip").style.display = "none";
}
else
{
document.getElementById("tooltip").innerHTML =obj.options[obj.selectedIndex].text;
document.getElementById("tooltip").style.display = "inline";
document.getElementById("tooltip").style.backgroundColor="#ffffcc";
document.getElementById("tooltip").style.paddingTop="1px";
document.getElementById("tooltip").style.paddingBottom ="1px";
document.getElementById("tooltip").style.paddingLeft ="1px";
document.getElementById("tooltip").style.paddingRight ="1px";
document.getElementById("tooltip").style.borderColor="black";
document.getElementById("tooltip").style.color="black";
document.getElementById("tooltip").style.borderWidth="1px";
document.getElementById("tooltip").style.borderStyle="solid";
document.getElementById("tooltip").style.top = screen.height;
document.getElementById("tooltip").style.left = screen.height ;
}
note: you have to change the top and left values by adding some constant number by trial and error method eg:
document.getElementById("tooltip").style.top = screen.height+500;
document.getElementById("tooltip").style.left = screen.height+20 ;
also check how the page looks at different resolutions.

You'll need to show more code than that - post the declaration of the SQL DS and of the grid, so we can see if they tie up ok - my bet would be that you've not bound the grid correctly, or AutogenerateColumns=false and no cols specified?

Hi,
I have 2 applications (apps1 and apps2) both using windows authentication.I have another main application called Login thru which i can log into the above 2 applications and this also uses windows authentication.
I would like to pass the session variables from the login apps to apps1 and apps2 with out gettting the login page to enter the values. Also apps1 and apps2 can be run individually without going through the login page.
Sessions donot work. Is there anyway to do this???
Any code or tutorial for the same will be useful
Regards

I need to dynamically instantiate an object using a string parameter, but don't know how to have the string evaluate as the name of an object... e.g.,
<br />
public class myClass <br />
{<br />
public Class_Master objMaster = new Class_Master();<br />
public Class_A objA = new Class_A();
public Class_B objB = new Class_B();
public Class_C objC = new Class_C();
<br />
public myClass(string nameOfTemplateClass)<br />
{<br />
this.objMaster.ContentTemplate = nameOfTemplateClass;<br />
}<br />
<br />
}<br />
So I then instantiate myClass specifying one of the ITemplates as my parameter:
myClass xyz = new myClass("objB");
"objB" is interpreted (understandably) as a string, not the object I wish to reference. Is there a method for evaluating a string literally? Like:
this.objMaster.ContentTemplate = eval(nameOfTemplateClass);

Why not use a switch/if-structure to instantiate the class you need based on the string?

That is in fact what I ended up doing as a workaround. However, I'm still interested in whether this is possible, as I encounter this situation periodically. I have used FindControl("stringname") for the times when I'm specifying a control, but there are times when evaluating a string as code might be useful; perhaps even composing an entire statement dynamically... but thank-you for responding with a workaround suggestion.

Hi ,

thank you

Hi,
When a control is created dynamically at run time, some information about the control is stored in the view state that is rendered with the page. When the page is posted back to the server, however, non-dynamic controls (those defined on the page) are instantiated in the Page.Init event and view state information is loaded before the dynamic controls can be recreated (generally in the Page_Load handler). Effectively, before the dynamic controls are recreated, view state is temporarily out of sync with the page's controls. After the Page_Load event has run, but before control event handling methods are called, the remaining view state information is loaded into the dynamically created controls.
In most scenarios, this view state processing model works fine. Typically, you add dynamic controls to the end of a container's collection of controls. The view state information stored for the dynamic controls is therefore extra information at the end of the view state structure for the appropriate container, and the page can ignore it until after the controls are created.
However, view state information about dynamically created controls can be a problem in two scenarios:
If you insert dynamic controls between existing controls.
If you insert controls dynamically and then reinsert them during a round trip, but with different values.
If you insert dynamic controls between existing controls, the dynamic control's view state information is inserted into the corresponding location of the view state structure. When the page is posted and the view state is loaded, the dynamic control does not yet exist; therefore, the extra information in view state does not correspond to the right control. The result is usually an error indicating an invalid cast.
Hope u understood the y we require ViewState.
