Forms Data Controls :: Trying To Make A Gridview Column A Thumbnail
Jan 22, 2010
I can get the file(image) to display, but it displays at a size that is too large for my use. Basically, right now, I'm pointing the ImageField to the first field in the grid that contains the url of the image. I could require the user to create a smaller image of the file but that seems a little excessive. Is there any way to control the size of the column displaying the image? Here is the html, we are using LINQ to get the data that is displayed in the grid.
I m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
i have gridview that shows some information i want to have column that be autonumber shows the row number of gridview.for example i have 7 row in gridview it show 1 for first row ,2 second row,3 third row,... how can i do that?
i'm bindng data to gridview using bound field.one column of gridview is linkbutton.if the text is more than the cell width then the gridview width is increasing automatically.for ex if i have text like "microsoft asp.net forums" then it's displaying the whole text.but i need that text like "microsoft.....".how to display like this in gridview?
How to set the GridView column fixed in width size whether there is data in the column cell or not. I try below code using "ItemStyle-Width" in the BoundField control to fix the column width but column became narrower if there is no data to display in it. Is this a no solution of ASP Gridview control ?
I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?Â
i have made a gridview which contains three fields, two textboxes and one combo box. ComboBox fetchs data from table(SQL) and when a combox box triggers, data related to combo must be added in two boxes. i did this throw another button, but i want this to be trigger directly when it clicks.
I have a gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:
[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
I have a requirement where i need to upload image files and display them as thumbnails on webpage. when clicked on thumbnial image the orginal uploaded image must display.iam in great confusion whether to make thumbnails dinamically on the fly when retrieving the orginal image or make thumbnails and save them to saperatefolder when uploading and save orginal image to another folder.
GridView, TemplateFields. Is there a way to have a column only appear in DataBound View, but not in Edit View? Leaving EditTemplate blank only blanks out the row, not the entire column.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
I am using GridView ,I want to do a validation like if i edit any one of the Cell in that column, it will through the validation when the sum of column value is more than 100. How can i do this validation?
After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.
As per my requirement, I am getting CompID, Company Name and URL from SQL database. I want to display just CompName and URL in gridvew. So, I need to hide the CompID in gridview. One way I can do BoundField field Visible to false but I need to retrive that compID id when user selected any of the row. if I set visible to false user wont see any compID in gridvew but I want access the selected compID also using SelectedRow.Cells[1].Text..
I have a large image....lots of them actually, I need to have shown as thumbnails while still allowing for full size viewing. I was planning on using:
http://nathanaeljones.com/products/asp-net-image-resizer/ to handle this for me, but I need something that also allows you to click on the image to view the original full size version in a jQuery style popup.
I have a grid view with 4 columns and 12 rows. Getting the row index is not problem; ;however, I cannot find a way to get the column index of the cell that i select.
