I have a gridview which has an image specified for the selectimageurl property.
Can someone advise how I can programatically change the image on a row per row basis?
I would ideally like to only change the image depending on the value of another column within the gridview.
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
View 3 RepliesI need to create a grid where the users can see all the memberships, and have a line of checkboxes for each existing role, and be able to check/uncheck roles to allow access authority.
I managed to build a datatable that adds columns and displays them properly, but I have not been able to programatically add columns to the grid based on whatever roles are stored in the system.
I can display the users and their roles by just specifying AutoGenerateColumns="true" when I do that, the checkboxes are grayed out, and the users do not want to have to click a button to open them up.
Here is what I can't figure out.
How do I programatically add columns to the GridView? I have some code in Pageload, but it doesn't work, so it is commented out?How do I turn on all the rows for the entire GridView to edit mode? How do I access the column name for the role they just checked so that I know what to add with the ystem.Web.Security.Roles.AddUserToRole(UserName, Role)?

View 2 Replies I'm trying to change the value of the language and culture values via a database entry and then appending the culture to the returned value. IE: "en" is in the database, I add "-CA" via VB code.When I hardcode the values, it does work no problem. However, appding the "-CA" makes it crash with the following error message:

Now, I'm retrieving the language value from a database and, since the information is used all over the web site, I cannot really change the data within the database.The following code is posted in the Default.aspx page, called by the master page.The function "siteSetLanguage" retrieves from the database the base language (EN/FR) and returns the value. Null values are checked for and if a null value is returned from the database, it defaults to EN.[Code]....
I do want to force UICulture to english as everything in the databases and external files are stored through the english canadian regional method.

Now i want to be able to let a users press the button, write a value in a record in the database and then change the red balloon to a yellow one. When the user wants (at any given time) wants the undo the value again the record should be rewriten again and the yellow ballon should be red again. Any tip is more than welcome :)

View 8 RepliesFirst off, sorry if this is in the wrong section. I have a gridview that loads from a SQL database. It has three columns, the first being a template column with a checkbox, the second being a name from the database, and the third being a field from the database related to that name. (the third column is empty). I want to be able to click on the check box in each row, and automatically have the third column populate with data that the user can select from a drop down list at the top of the screen or something. I am using VB, and I basically just need a way to make this checkbox, add a value from somewhere into the database. (Also, I know that I can just use Edit in the gridview to change data, but there will be a long list, and that way gets quite time consuming) I hope this makes sense, if not I can try rewording it.

I would like to change color of the gridView depending on the value from table that is bounded to the grid. I actually don't show this value on the grid. I tried by using additional field with visible=false, but the cell is string empty in this way. I don't know how to solve this in some other way?
I used this code, but as I said the value is empty:

Is it possible to solve this by getting value directly from bounded table and not from rows cell?

Nw i want to change the TempPwd checkboxfield from another aspx file namely NewUserLogin.aspx, So is it possible? The idea behind doing this is, as soon as the user enters a new password in the NewUserLogin.aspx page, the checkboxfield in the GridView of CustomerSetup.aspx file should be unset.
I'm attempting to bind multiple datasources to a single Gridview. Can someone direct me on how to change the below <%# Bind("") %> programatically in the code behind. For example, change "HRID" to "PayrollID" to account for a different column. the dataSource binds to the Gridview so the Rows will not be created yet.
I know how to accomplish this with a boundField, but I'm having issues with setting the text of the label in the ItemTemplate.
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:Label ID="lblHR" runat="server" Text='<%# Bind("HRID") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblNewID" runat="server" Text=""></asp:Label>
</EditItemTemplate>

How to change the skin ID of the dynamic controls
View 2 RepliesThis is an ASP.NET 3.5 project being created with VS2008. One page contains a gridview with six columns. One of the columns displays standard, 17 character , Vehicle Identification Numbers (VIN). The VIN numbers display normally when the page is rendered. However, when the gridview is exported to Excel, the VIN numbers change. For example, in the gridview, the VIN might be 12345678912345678But when the gridview exports into Excel, that same VIN becomes 1.23457E+16The value of that Excel cell changes to 12345678912345600, changing the last two digits from 78 to 00. It does this for every VIN in the gridview table.I did some Googling but couldn't find anything specifically on this issue. Has anyone seen it before? Is there a way to format the column in the gridview so that Excel will accept it as literal text? I tried programmatically adding a style called 'text' to that column but that had no effect on the outcome. All of the other columns are behaving normally.
View 3 RepliesI have a simple GridView in my page which it bound to Database using Connection String in vb.net.(I am not using SqlDataSouce of Asp.Net)

I have even used the GridView1.Columns(0).HeaderText = "some text"
im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.
After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?
I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
