How to output a web control so that it can be postbacked from the page?
I write the code like this:
LinkButton btnTest = new LinkButton();<br />
btnTest.Text = "Test";<br />
btnTest.Click += new EventHandler(btnTest_Click);<br />
StringWriter sw = new StringWriter();<br />
HtmlTextWriter htw = new HtmlTextWriter(sw);<br />
btnTest.RenderControl(htw);<br />
lblTest.Text = sw.ToString();
Now the control could be outputed by HTML code,
but it cannot be postbacked from the page.
It be outputed like a normal text, not a LinkButton.
I want it can be clicked, and raise the click event.
So, what can I do for it?

Hi,
btnTest.PostbackUrl="specify to which u want to postback";
I hope this will suffice ur requirement.
Happy Programming.

No, it doesn't it!
At last, the server output the HTML's code like <a>Test</a>.
So the LinkButton cannot be clicked!!!

First if condition getting executed implies the value of flag = 0
hence third if condition would be false and hence the inside code will not be executed. 
|
|
|
|
|
I guess it can go inside only one if condition either if(flag == 0) or if(flag ==1) and since its going inside flag==0 it shows flag value is 0 then it wont go inside other if condition and its working properly.
What is ur problem?
|
|
|
|
|
but here always seen flag==0
if i will select date that time also flag==0 how?

Its working fine iam retrieving images, but ....
For example : customer may upload 2 - 3 product details with image so we have 10 options to image upload.
So the condition is given like if i click button in new page by checking for karnataka state than all the product pictures should be displayed. because the condition iam checking for karnataka(like that i have to create 26 stats)
here iam receiving all the images as same.(it should be come different images according to that respective products.

Your question doesn't really make sense. Are you saying that every product is being rendered with the same image? If so, how are you rendering the images? Check how the URLs are being constructed. You would need to post your code if you want further assistance.

Each and every product having different images, but iam receiving all same images, if i go for the condition.
Html code :
<asp:image id="im1" runat="server"> <asp:image id="im2" runat="server"> <asp:image id="im3" runat="server"> code Behind :
protected void Button1_Click(object sender, EventArgs e)
{
con.Open();
SqlCommand cmd10 = new SqlCommand("select * from onlinegoa2 where state='Karnataka'", con);
SqlDataReader dr10 = cmd10.ExecuteReader();
while (dr10.Read())
{
string x = dr10[4].ToString();
string FileName = x.ToString();
im1.ImageUrl = "./uploads/" + FileName;
}
con.Close();
con.Open();
SqlCommand cmd11 = new SqlCommand("select * from onlinegoa2 where state='Karnataka'",con);
SqlDataReader dr11 = cmd11.ExecuteReader();
while(dr11.Read())
{
string bb = dr11[6].ToString();
string FileName1 = bb.ToString();
im2.ImageUrl = "./uploads/" + FileName1;
}

For each iteration of the loop, you are changing the ImageUrl property of the same object. You need to update the object reference im1 for each iteration of the loop so that it points to the image object that corresponds to the current row of data.
It would be better to use a data-bound control like a Repeater and declaratively define data binding expressions in the template designer.

Your second and third if conditions are missing their trailing parentheses. I presume this is a typo, otherwise your code wouldn't compile.
funSearchFromDate() will only be executed if dtpFrom.Text and strFromData are equal. This comparision is case-sensitive; use String.Compare if you want to do a case-insensitive comparison.
