Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

Web Forms :: User Control Does Not Let Me Assign Values Into Text Boxes?

Dec 14, 2010

(using c# and .NET 2008):

I have a main web page and added a user control inside it. The user control has some textboxes. The problem I have is when I populate the textboxes with the data that is in the DB, they do not show the values. The strange thing is If I change the property of textboxes ReadOnly to TRUE, they show the values. The problem is that I need them to be ReadOnly=FALSE.

Forms Data Controls :: How To DataGrid SelectIndex Inside A DataGrid

Sep 22, 2010

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.


I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.

I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

Forms Data Controls :: Displaying Thumbnails In Datagrid Alongside The Table Data?

Oct 31, 2010

I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.

At present I have added the following to my datagrid:


So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:

Forms Data Controls :: Populate A Datagrid On Selection From A Drop Down List?

Mar 17, 2011

This is my first post as a newbie to asp.net.

I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.

What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.

So far my edit page has a datagrid with the following code:

Forms Data Controls :: How To Display A Multiline Text In A Datagrid

Feb 20, 2010

i want to display a multiline text in a datagrid i insert the text in a textbox outside the datagrid.

the textbox wraps the text if it doesnt fit to the textbox length.then i push a button and insert that text in a database. then i want to display this text in a datagrid.i use two options in a label or in a textbox in a templatecolumn but with the textbox <asp:textbox ID="textbox1" runat="server" style="overflow:hidden" Font-Size="15px" BackColor="#FFFFC0" TextMode="multiline" Width="750px" Wrap="true" borderstyle="None" BorderWidth="0" Text='<%# Databinder.Eval(Container.Dataitem,"text_caption") %>'></asp:textbox>

i receive only the first two lines

and with the label
<asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>

if the text is too big without an enter(that text wraps in the outside inserting textbox) then the datagrid width becomes too big although the text is diplayed normal with new lines so in the datagrid i have much space without characters the textbox that i use to insert new text is here <asp:TextBox D="tbox_text_caption" runat="server" Height="232px"
Style="left: 400px; position: absolute; top: 8px" MaxLength="750" TextMode="MultiLine" Width="752px"
Wrap="true" TabIndex="5" BackColor="#FFE0C0"></asp:TextBox>
