View 33 RepliesI am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.
View 3 RepliesI have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.
EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole =
new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi
is the webform code behind partial class.
CheckBox chk =
new
CheckBox();
chk.ID = _columnName;
chk.DataBinding += new
EventHandler(chk_DataBinding);
//Attaches the data binding event.
chk.AutoPostBack = true;
chk.CheckedChanged += new
EventHandler(ealmsapprole.Dyn_CheckChanged);
container.Controls.Add(chk);
chk.Enabled = true;
This is the code for the event Handler
internal
void Dyn_CheckChanged(object sender,
EventArgs e)
{
string err =
"";
try
{
if (lblAppID.Text !=
"")
}
that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.
I made a usercontrol consisting of an AJAX tab control, a textbox, and a gridview. The gridview is pulling data from a SQL database. When the gridview is outside of the tab control and I begin to enter text into the textbox, quicksearch begins to filter the information in the gridview. When i put the gridview and textbox inside an AJAX tab control quicksearch does not work. How do i need to structure the textbox and the gridview on an ajax update panel to get it to work?

I am also using a dropdown box and a textbox for people to search within a particular area from the dropdown list.
Now, I would like to be able to highlight the keywords in my gridview table. I searched around on the Internet and found a lot of samples, but they are all related to the Gridview <templates>, however, I am using <BoundField> and sqlDataSource.
I just cound not figure out how can I add this highlight function to my current search function?
So, one of my end-users would like the option to search for a keyword and have all of the records that contain that keyword show up in a gridview. Is this possible? How would I do this? Are there tutorials somewhere?

I have configured a datasource for gridview1 to execute a Stored Procedure on a SQL Server Database passing a parameter with the value from textbox1.

View 1 RepliesI have gridview that I am filling with records from SQL database. However, I want to populate the gridview with records that match text search criteria. In other words, I want to be able to key in a word like "network" in a text box, pick up the text, read records and pick up on the records that match that criteria. I am doing fine with building the gridview but I am a bit new to this and I don't know what I do to do text search.
