Forms Data Controls :: Images To Conditionally Appear In Gridview?
Sep 1, 2010
I've got this gridview with a column labeled "Client Comment" that displays a clickable little icon when there is a client comment in the database. The problem is the icon is appearing whether or not there is data in the DB (except I don' t think it does when the DB value is null.)
How can I make it so the icon only appears if there is a comment in that database field? With code behind (if so VB) or in the tag?
Then I am adding boundfield to gridview for all 4 columns. Now I want to check if "Type" column contain "Sales" thne do not show "Manager" columns. Let me know can I do this?
I am facing a situation where I have to disable GridView field (in EDIT mode ) conditionally.
Here is the situation,GridView has 5 fields "Product Name" "Small" " Medium" "Large" "XLarge"
Here is the problem, application has section where user activate/deactivate sizes (SMALL,MEDIUM,LARGE,XLARGE). Suppose User activates "SMALL" and "LARGE". Now When the GridView is populted normally, I don't have to disable any fields. But when the user clicks "EDIT" on GridView row, I want "MEDIUM" and "XLARGE" fields to appear as disable.
Here is what I know
1) I will have active sizes in SESSION ... in the above case (SMALL and LARGE)
2 I know I have to catch GridView_RowDataBound and then I have to check for the edit mode for the row.
I have created a gridview and added a headertemplate field inside templatefield. Inside header template field I have added a button and a condirmbutton extender. confirmbutton extender uses modelpopup with ok cancel. This works fine but with one problem. I want this popup to open on button click only if user has checked atleast one checkbox from gridview. So far it shows this modelpopup everytime even user hasn't checked anything.
i have the following scenario, i have a column of a gridview that shows me a text telling me is the user is allowed or not to access to some page, but now i just showing allow and deny, but i wanna show images that represent me the action, how can i do that?
For this I am using ASP.NET 4.5, C#, and Entity Framework to SQL.
I have some sections of my site where users can make multiple entries and can optionally upload attachments. There is a page where the user can see a gridview that acts as an overview of the entires. I have been asked to display a column with a paperclip icon if an attachment exists.
The way the database is structured, the table that holds the entries has columns like this:
The attachments are in another table. For this table the attachmentId will hold an Int32 or be NULL (no attachment). My current query looks like basically like this:
var query = context.applications.Where(c => c.id == applicationPrimaryKey); var results = result.educationUniversities.ToList(); gdvEducationUniversity.DataSource = results; gdvEducationUniversity.DataBind();
I somehow need to create a condition where an image of a paperclip is shown if the attachmentId value is not Null. Optionally I imagine the query could be re-written to return a true/false value based on if the attachmentId value is null though I'm not certain how to do this.

How to redirect a page to a particular website link( links are saved in database) using database on button click, for particular DropDown value i.e, External.

I have a gridview that contains columns of electrical specification (value, resistance, etc.). The rows are populated with archival data from previous versions of th same part (rev A, rev B, etc.).
The question is: is there any way for me to review each row and set the font color to red if the value is different from the cell below, or above? This would highlight where changes were made to each individual revision of a part from the previous version.
I am trying to delete row(s) from the DataTable conditionally but I cant.
Actually I have DataList with CheckBox (default value checked=false). I am bindind DataList at run time using DataView (Dataview is created fromDataTable).
I also have <asp:Button ID="btnDelete" ....> which I am using to delete checked items in the DataList (But this functionality is not working).
The user first "checked" items in the DataList and click the the button "btnDelete". Here nothing is being deleted (?) and the DataList appears with all the items"unchecked" (even those which the the "checked" by the user). protected void btnDelete_Click(object sender, EventArgs e) . In this function I am checking state of the checkbox before deleting the row in the DataTable.
On PostBack generated by the "btnDelete", DataList appears with checkboxes unchecked therefore nothing is being deleted
I'm trying to conditionally hide 2 link buttons within a Gridview(gvPosts), ModifyButton and DeleteButton. I want the two buttons to hide in every row where the currently logged on Username is not the same as the Username in gvPosts' lbEmpID, a LinkButton control in the same row. Unfortunately the code is hiding the buttons in every row, including the one where lbEmpID.text = Profile.Username. My code is below, what am I doing wrong?
Dim lbtn As LinkButton For Each rowItem As GridViewRow In gvPosts.Rows lbtn = DirectCast(rowItem.Cells(0).FindControl("lbEmpID"), LinkButton) If lbtn.Text <> Profile.UserName Then Dim Modify As LinkButton Dim Remove As LinkButton For Each rowItem1 As GridViewRow In gvPosts.Rows Modify = DirectCast(rowItem1.Cells(0).FindControl("ModifyButton"), LinkButton) Remove = DirectCast(rowItem1.Cells(0).FindControl("RemoveButton"), LinkButton) Modify.Visible = False Remove.Visible = False Next End If 'If chk.Checked Then 'Response.Write(chk.ClientID + "<br />") 'End If Next

I'm modifying an existing application. I need to be able to bind the Text property of an asp:DropDownList control to one of two fields when the page is rendered. The existing code is like this:
[Code]....
I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.
using a repeater to display multiple 'comments' related to a parent database entity (a 'task' in my case). When the user creates these comments they can optionally attach a file. Now, I'm working on the page that lists these comments and I'm not sure how to go about displaying the link to the attached file, if one is present. There may not be a file. The database record that contains the comment will also contain the url to the file if one was attached.
what are my options for this? I would like to just display a link to the file after the comment content, only if a file is available.
