View 2 RepliesI'm using a searchoption on my website. (language = VB)
The user can choose a searchcriteria out of a dropdownlist (Artist name, Description, Price, Genre, Type) . If the user selects one of the options in the dropdownlist the correct textboxes are shown.
For example: if the user selects Price he gets two textboxes (one for the min price and one for the max price) if the user selects Artist Name he gets one textbox
The dropdownlist and the textboxes are put into an updatepanel. The searchbutton is outside the updatepanel.
Now for the problem:
If the user doesn't fill in a textbox and presses the searchbutton, the backcolor of that empty textbox should be turned red. The searchbutton is set as a trigger and the panel is updated on the buttonclick, but the colors don't show.
In the clickevent of the button I've said the following code:
If txtCriteria.text = "" then
txtCriteria.backcolor = Red
Else
txtCriteria.backcolor = White
End if
Quite a simple piece of code. This works if I remove the updatepanel from my page, but I'd like to keep the updatepanel because it's really nice :p.

I have a gridview control that has a different background color for alternating rows (done using cssclasses). In the RowDataBound event code, I want to change the background color of a ListBox control in one of the cells to match the row color. I have tried the following (in blue), but it does not seem to work. The listbox control still remains with white background. How may I determine the background color of the row so that I may set the ListBox background to match?

A corollary question is, "How may I programmatically reference an item within a CssClass?" For instance the CssClass is named "datagrid." How do I programatically retrieve the value of "background-color" that is defined in this CssClass?
What I need to do is perform some kind of decision statement and when true I need to change the backcolor of a treenode to grey, so that it has a grey box around the whole text. There is no backcolor property for the tree node and I don't need it applied all the time so I don't think a CSS class will do this.

I need to be able to change a row's back color in the GridView based on the value in each row's second cell.
But, I'm having some trouble looping through each row. I thought the following might work:
VB.NET Code:
For Each gvi As GridViewRow In Me.gvTechPPE.Rows
ClientScript.RegisterStartupScript(Me.GetType(), "New Entry", "alert ('" & gvi.Cells(1).Text & "')", True) Next
I ran that just as a test. An alert pops up, but only for the first item in the GridView. All the others are skipped.
I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.
The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.
The "making the GridView row display it" part is the one that's giving me a hard time.
What's the best way to do this?
Is it possible to loop through a gridview and based on if a checkbox is checked, then change the backcolor to that current row? I have gave a few attempts, but luck.

in this artical your using 3 text box inside the grid for searching grid data .my question how to fix the size of these textbox? because of this textbox what i am using in my grid, my gridview became so large.and even its not looking good.
I have this gridview, what I wanted to do is that when the page_load or when the page index changed when the user clicked "Next or Previous" the label change with the gridview. The label and the textbox get the information from the gridview row. It's working but it's alway lagging behind the changed gridview page. Ex: When I click next nothing happen, when I click previous the label changed to the info on the "next" page. O_0This is the code behind.
