i have a repeator control that is bind to a dataset, one of the field is image path that is bind with <img src tag. Now the problem is so of the articles are with out any image, how can i make sure that <img tag only render when there is an image name exist?
[Code]....
I am unsure on how to perform this task, what i need to do is make a gallery with tagging. I need this as it is a requirement for the project. Each user will have there own gallery and be able to upload and delete images from there gallery. I already know how to insert and select images from a database. I will then display the gallery using a data repeator with paging, I am sure i can google an article for data repeator with paging.
My challenge is, when the user wants to save a image to there gallery, he must 1st upload the image and then i must some how display the image, when the image is displayed, i will have a text box where they can add tags, this textbox will save in the tag table for that user_id, picture_id and the tag will have an id also. I am unsure on how to do this When he clicks save, i wanna insert the image into the table, and the tag. If he does not click save, then nothing should be saved. Now the 2nd part.
In the data repeator, i want a modal window to popup when they click an image, this modal will have the image and the respective tags that where saved for this image, I am unsure how to this.
i want use labels in Repeator ,can any one tell how to bind.
please send the source code.
I am trying to debug one of the project in which i need to show the data for one of the particular cell in two lines.
This Repeator control Exists in a user control and aspx is calling this User control for displaying the data.
Here is how my code looks:
[Code]....
I have a repeator control which is displaying the search results and it contains 50 Records.Paging is Enabled for the Repeator control and hence i am able to see 10 records at a time.
Now my requirement is :
When ever the user clicks the browser back button after going to the the Last set of records from the result set (41-50 records) in the Repeator Control,the Page is displaying the First set of Records(1-10).
Expected Result :
Page has to display the Previous result set (31-40) after clicking the browser back button.

I got this problem that I'm trying to repeat an imagebutton inside a repeater so I can add an command argument to it...
But the image butten fails and I can at the most get it to write "Subit Querry" att the fields where I'm trying to get the images to appear. I havent that much usefull code for this after trashing the most in frustrations. but this is what I got.

So what I'm trying to do is put a Imagebutton around my <%#Eval ("img_name") %> so I can get the src from my DB.
I'm working on a bug in our application and I cannot figure out why this problem even exists. We have a custom DataGrid control that inherits from the standard asp.net DataGrid. In the grid, we have a ButtonColumn as the second to last column. The code for that column is:
[Code]....
The problem is that the "alt" text does not show up at all. There are 2 other images in this DataGrid, and the alt text shows up just fine in those.
I am currently using following code to set alert on required column of my grid. When I change button type to Image the alert appear after completion action.
My code is below..

I am creatin a server control where some controls are being rendered inside `protected override void Render(HtmlTextWriter writer)`
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo1");
writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button1");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo2");
writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button2");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
This way buttons are rendered on design view as well. The problem is that number of buttons to render is dynamic based on data in xml file (even if the data was static, the number of button is about 12 and I don't think it is wise to copy paste the same code above 6 times...). I thought by using loop for that:
int i = 1;
foreach (Button button in tb.Items)
{
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo" + i);
writer.AddAttribute(HtmlTextWriterAttribute.Value, button.ButtonValue);
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
i++;
}
tb is defined in OnLoad; On run time it works, but on design time I get error: > Error rendering control. And control is not being rendered.

View 2 RepliesWhat I am dealing with is a collection of data from 3rd party sites, some xml, some thumbnail images already.I essentially have an asp page that uses vb to collected the data and display it with some minor formating in a <div>, I use a literal control and a stringBuilder to put together the html and output it to the literal.
Here is my asp.net code
<form id="form1" runat="server">
<asp:Literal ID="Info_literal" runat="server"></asp:Literal>
</form>[code]...
So what I've been trying to do without any luck is have the output dump into a stream, then render the html into an image from that stream.I have looked at most of the links that have been posted in simular threads, and none of those are simular to exactly what I am looking for.

How to call different images in <asp: Image> tag for every row of gridview.I used below code as per my requirement (HTML code):
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Caption="Customer List" EmptyDataText="You have deleted all records in customer list">
<RowStyle Height="40px" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
[code]....
Only difficulty im facing is how to bind different images in "ImageUrl" for every row of Gridview.Note: Images are not saved in DB.
I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:
\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.
pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg
But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg
I suspect this is related to the problem.
