C# - Set Attribute With JS And Grab It By ControlID In Code-behind?
Aug 24, 2010After postback, attributes are cleared.
So how can I send an attribute applied to controlID via JS to the next request page?

I am trying to allow users to grab their stored procs and call certain ones from within code. I can get the stored procedures and then fill a dropdown with them, but what I cannot find at this point is how to get the parameters that each stored procedure needs. I would like, once an SP is chosen from the dropdown to make a call to the db with that sp name and grab its paramter list so I can report what needs to be sent in to the user.
View 1 RepliesI have an ASP.NET Webforms site that is regularly having features added.The majority of time a new WebControl is added to the page and I need to increment the TabIndex to all subsequent controls on the page.I'd prefer a more robust solution than choosing an arbitrary gap between the initial assigned tab indexes. Setting the tab indexes using the designer tab order functionality is one option but I'd prefer to stay in the source view.Ideally, if I had, for example, three check boxes I'd like to be able to define the tabindex based off the previous controls tabindex. Then I'd only need to insert the new control and change one existing control.For example, add a new property TabIndexAfterControlId to WebControl:
<asp:CheckBox ID="checkBoxA" runat="server" TabIndex="1"/>
<asp:CheckBox ID="checkBoxB" runat="server" TabIndexAfterControlId="checkBoxA"/>
<asp:CheckBox ID="checkBoxC" runat="server" TabIndexAfterControlId="checkBoxB"/>
I have a TextBox in my page
<asp:TextBox ID="TextBox1" runat="server" ReadOnly="true"></asp:TextBox>
I am not able to get the changed value ( I have attached a ajax calender with this textbox)
in code behind because it is readonly
I can do this using TextBox1.Attributes.Add("readonly", "readonly"); or I can get the correct last value using Request.Form[TextBox1.UniqueID]
Why value is available when use code behind attribute add

View 1 Repliesis there a way to set datapager controlid to control in other page.
For example: we have 2 pages - page1 with datapager1 and page2 with listview and datapager2. If i put datapager2 in page2 and set pagecontrollid to listview everything is ok. i wonder is there a way to set programatically the same in page1 so we could get te pagecount for other page.
Web Forum is a perfect example - we have posts count, when we click on datapager in topics list, it redirects us on selected page with posts for selected topic (i assume its on other page).
string iframeSrcPage = iframeMain.Attributes["src"];

I've created my user control. In the page I've written my markup as follows:
<uc1:myUserControl id="myUserControl1" Enabled="true" runat="server" />
I cannot get the value Enabled="true" in the code behind during page load.
normally on would use the following :-
aspx page:-
<a ID="a1" href="javascript:void(0);">Link1 </a>
code behind:-
a1.HRef="www.mySite.com/mypage.aspx";
how do u set this HRef attribute in case the anchor tag is within a repeater ?

i am creating a datagrid dynamically and having one column hyperlinkfield i set the following
HyperLinkField hFld = new HyperLinkField();
hfld.navigateurl="default2.aspx";
hfld.target="_blank";
but iam not able to specify the window size and options so i thought to use the javascript window.open how to have the below in code behid ?
<asp:HyperLink ID="HyperLink1" runat="server" onclick="javascript:w= window.open('test.aspx','mywin','left=20,top=20,width=500,height=500,toolbar=0,resizable=0');">new Window</asp:HyperLink>
I have a multiline textbox that by default, is set to ReadOnly. I would like a button on the page to change the control to allow it to be edited. I would like this code to run on the client side because the page renders slowly and I'd like to avoid the post back.
The problem I'm having is the javascript code that I wrote to remove the readonly attribute appears to have no effect. I posted a stripped down example that illustrates the problem for your review.

In the ASP.NET MVC site that I'm writing, I'm building a generic Error Action that is routed to by an HttpModule, following this tutorial. In this Action, I will return a View corresponding to the status code that is applied to the response inside the HttpModule (after doing this, the module transfers the request over to the Action in question).
That's all good, except that I want to implement caching. I don't want to use the OutputCache attribute without filtering/varying, because that would mean that the page would be cached once. I want the page to be cached once for every possible status code.
Is it possible to somehow filter/vary with OutputCacheAttribute's properties, so that each Response.StatusCode is cached separately?

I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows
var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD")
join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT")
on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT")
select new
{
SlotName = (string)SLT.Attribute("NAME").Value,
SlotValue = (string)SLT.Attribute("NAME").Value
};
In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?
