Question

I have an issue regarding link button, On my website i have got a product for sale page, which has a ryt side bar with filter options
while the left side bar shows the filteration results.
On my ryt sidebar i have used accordion with the repeater control which display the searching criteria from database.
For instance I have 2 searching criteria model and price , under model accordion there are three models, what I want to acheive is
when a user clicks on that specific model , the page should run a query with respect to that click and show bind the results on the
repeater of the left side bar, I know the query to get the results but I dunno how to get the value
of that hyper link button, coz these buttons will be dynamic it can be 3,4 or 10. how will i get the clicked hyperlink value
so that I can run the query depending on the model selected.
Any help or tutorial will highly be appreciated.

Answer 1

Set the CommandArgument of the LinkButton.

Then to access the CommandArgument:

protected void lnkButton_Click(object sender, EventArgs e) {
    LinkButton _sender = (LinkButton)sender;
    string argument = _sender.CommandArgument;
}
