i have a RadioButtonList and the list is bounded by a datasource.
By default, its default selected item is empty, i would like to know how i could make the first thing it databounds into, should be the selected item.
So I am using a formview that gets in Update mode with a bunch of values from a sqldatasource --- but I want to fill a couple dropdowns with data from the database --- but I cannot figure out how to bind the data to the dropdown box FIRST and then select the value in that dropdown box... but I keep getting an error that the Selected value is not a part of the dropdown (I assume because the sqldatasource is trying to bind BEFORE I can get the dropdown box bound).
IE -- when I load my values, lets say a 'Crop' comes back as 'Corn' ... I want to download the available crops from the database (ie. corn, beans, wheat, okra, etc.) and then set the selected value as CORN.... SO HOW do I get the dropdown filled BEFORE I try and bind the selected value?

I have a data gridview with two columns (Databound- HTML tags), very similar to the one of twitter,the second column populated as follows:

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
i have a problem in this code

How I can select a value from RadioButtonList which filled from a webservice?
I have a dropdown list which is bound to a gridview. I would like to add a dropdownlist item which, when selected, will default to displaying ALL gridview rows. So I would like as the first dropdown list item "All Items" and have this as the default.

I would like to select an item in the list programmatically via a client-side jquery function like this (simplified version):

Ideally, there is some function - in the above code I have proposed selectItemByValue - that selects an item in a RadioButtonList by a given value. Does jquery have a similar function built-in? If not, how should I go about implementing the desired functionality?
i have a FormView, and i already have a Label control that gets the value of theselected propery inside the FormView, so each time the FormView displays data, i have a Label control that displays individual values, according to the value of the FormView, here is the code:

What i would like to do is to know how i could add a DataList instead of a Label, and then each time the FormView databinds an item, to show the value of the DataList How would i go about doing that?
I use below code for binding CheckBox from database

I have a radiobuttonlist inside a datalist itemtemplate and i need to bind the radiobuttonlist dynamically from database I have tried to bind it inside itemdatabound event of datalist but it the result is always duplicated according to the fields in teh database.

I have a DataBound DropDownList that is loading fine, but i'd like to insert another item that says "--Select--" or something instead of having the first DataBound item automatically display.
Is there an easy way to do this or do I need to manually add a dummy item?

I want to render something like this (with ASP.Net Controls in the codebehind):
<ul>
<li class="first"><h1>This is a caption</h1></li>
<li><a href="#" title="" target="_self">Foo</a></li>
<li><a href="#" title="" target="_self">Foo1</a></li>
<li><a href="#" title="" target="_self">Foo2</a></li>
<li><a href="#" title="" target="_self">Foo3</a></li>
<li><a href="#" title="" target="_self">Foo4</a></li>
</ul>
<ul>
<li class="first"><h1>This is a another caption</h1></li>
<li><a href="#" title="" target="_self">Foo5</a></li>
<li><a href="#" title="" target="_self">Foo6</a></li>
<li><a href="#" title="" target="_self">Foo7</a></li>
<li><a href="#" title="" target="_self">Foo8</a></li>
<li><a href="#" title="" target="_self">Foo9</a></li>
<li><a href="#" title="" target="_self">Foo10</a></li>
<li><a href="#" title="" target="_self">Foo11</a></li>
</ul>
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.
Can any one let me know about the below issue. I have a page which has three labels, say startdate,enddate and username. My issue is if the user doesnot select any of the above three then a message gets displayed as "Please select one search criteria" or if the user doesnot enter the date in correct format then i dispaly "Please enter date in mm/dd/yy" format. But what is happening is first time if the user doesnot select any then "Please select one search criteria" is getting displayed and after this message gets displayed if the user enters wrong format of date then both the messages are displayed.
View 5 RepliesI have gridview. some columns are data, and some are link buttons. now, I need move these link buttons to a hovermenu. this is done. but I got a javascript exception, and it is because if there is no row was selected in gridview, it will pop this.
so, the question is: how can I select a row in gridview without select command? simply by code?
Is there any way to do this? I can't find anything to latch on to.
View 2 RepliesI have a web page like the page in the link given below.
[URL]
In this there is filtering colums. I want to display these in the left side of the list not on the top.
I have a content page that displays search criteria in a div. I would like to hide the criteria div when results are returned, but keep it visible if no results are found. I have code in the DataBound event for the gridview that displays the number of rows returned from the query which works fine. To show the search criteria, I have a RegisterStartupScript which calls the javascript function to show the div. Even though the RegisterStartupScript code is executed, the javascript never runs (I put an alert in the function that never fired). Is this a lifecycle timing issue? I just don't see how I can register the javascript earlier in the page lifecycle if it is. I would think this is a very common requirement.

I have a problem about BulletList. I'm using jQuery drag&drop to fill a BulletList. Since controls does not render when datasource is null, user has no <ul> to fill. Is there any way to force BulletList to render an empty <ul> when datasource is empty ?
View 4 RepliesI have trouble with the sequence of events on my page. I have a button, which on its onClick event calls a method, which posts data to a database, and causes a postback. But on the same page I have a repeater which uses the data that is being modified by the button. I would need somehow the buttonclick event occur "earlier" than the databinding in the repeater to show the correct data.

View 7 RepliesI am fairly new to asp.net programming. I found this custom control that uses ajax to update the contents of the control and it is working perfectly. However, I need to access some of the asp.net labels and images in the databound event so I can set their values/properties appropriately, and am not sure how to go about adding additional code or accessing these in my custom control (I have been googling endlessly with no results). My code for the custom control is below.

I've got a formview with controls in different template views and I have a query just out of curiosity.
In my edit template I've got for example:
<asp:TextBox ID="IsPrestigeTextBox" runat="server" Text='<%# Bind("IsPrestige") %>' />
<asp:CheckBox ID="IsPrestigeChkbx" runat="server" />
and then the same code exactly in my insert template:
<asp:TextBox ID="IsPrestigeTextBox" runat="server" Text='<%# Bind("IsPrestige") %>' />
<asp:CheckBox ID="IsPrestigeChkbx" runat="server" />
However, the databound items seem to be allowed to have the same ID whereas the non-databound checkboxes arent.
What's going on there?
