What is the data for the gridview? You could switch the icon based on a true/false boolean in your dataset?

Santosh Kokatnur 31-Mar-16 3:57am

@FARONO... Just is manually added.... ya as you said, boolean in dataset. Can you please provide me the code?

Solution 2

using DataGridViewImageColumn [^] you can create it.

Add the relevant images to the resources Folder How to: Add or Remove Resources[^]

C#

DataGridViewImageColumn imageCol = new DataGridViewImageColumn();
dataGridView2.Columns.Add(imageCol);


for (int i = 0; i < dataTable.Rows.Count; i++)
{
    var flag = dataTable.Rows[i]["BooleanColumn"].ToString().ToLower() == "true";

    if (flag)
        dataGridView2.Rows[i].Cells[0].Value = WindowsFormsApplication1.Properties.Resources.image1;
    else
        dataGridView2.Rows[i].Cells[0].Value = WindowsFormsApplication1.Properties.Resources.image2;
}

Can you please provide me Full code?

Karthik_Mahalingam 31-Mar-16 5:17am

what do you mean by full code.. I have created a sample app like this

private void Form1_Load_1(object sender, EventArgs e)
{

DataTable dataTable = new DataTable();
dataTable.Columns.Add("flag");
dataTable.Columns.Add("Name");
dataTable.Rows.Add(true, "aa");
dataTable.Rows.Add(false, "bb");
dataTable.Rows.Add(true, "cc");
dataGridView2.DataSource = dataTable;

DataGridViewImageColumn imageCol = new DataGridViewImageColumn();
dataGridView2.Columns.Add(imageCol);

for (int i = 0; i < dataTable.Rows.Count; i++)
{
var flag = dataTable.Rows[i]["BooleanColumn"].ToString().ToLower() == "true";

if (flag)
dataGridView2.Rows[i].Cells[0].Value = WindowsFormsApplication1.Properties.Resources.image1;
else
dataGridView2.Rows[i].Cells[0].Value = WindowsFormsApplication1.Properties.Resources.image2;
}

}

its difficult, i dont have time to break my head on it.
post it on cp, someone will help you..

Karthik_Mahalingam 16-May-16 1:51am

when will you learn ?
i would suggest you to break your module into N number of pieces and do bit by bit, this is the only way to achieve any big task, i follow this way..
take a pen and paper, sit and analyse your problem and do some rough calculations on your module, objects, and related dependencies and try to build your stuff,,
nothing wil work by asking for help on whole project or delaying..
slow and steady wins the race..
start doing all the best..
I know your problem and i can build a solution too, but this is not my job. i am not your servent. I am helping others in CP, i like this very much. but there is a limit for everything and you have crossed that.. so i put an end to it.
start working... start coding..

Santosh Kokatnur 16-May-16 1:56am

ok bro... thanks! i will do it.

Karthik_Mahalingam 16-May-16 2:27am

again again, you are doing the same mistake,
bro , he no one is ready to sit and debug your code.. pls understand this..
"how to get treeview data to gridview" by seeing this no one wil open the question only..
approach it in a easier way..
say for ex :
"How to get Selected Node and its child Value from treeview "
" hot to iterate the sub nodes in a Node from Treeview "
" Get Values to sub nodes inside a node from treeview"

see once you get the values , you can store those inside a table or list and you can bind it easily, that is your part.. dont add this in the question which make the reader too complicated...

Santosh Kokatnur 16-May-16 2:29am

ok bro. but i have taken treeview for logical drivers na. is it possible to bind?

Karthik_Mahalingam 16-May-16 2:34am

:(post one by one.. dont put all your question in one shot..
and post only the relevant code for your question and write more description to the question so the viewer will understnd the issue and provide solution for it..
have some patience bro :(

Santosh Kokatnur 16-May-16 2:37am

ya bro. Thank you so much :( I have one query... I have did another treeview application, in that childnodes are not get selected. if you are free then please connect on tv. if its okay , then u can. i don't want to disturb you more.

Karthik_Mahalingam 16-May-16 2:41am

Is there any ways to add icon telling "LATEST" for the latest announcement in the data grid view using c# asp.net ?

Sagar Haridas Shinde · Accepted Answer · 2016-03-30T23:07:00

Solution 1

C#

DataGridViewImageColumn ic= new DataGridViewImageColumn();
 ic.HeaderText = "Img";
 ic.Image = null;
 ic.Name = "cImg";
 ic.Width = 100;
 DGV.Columns.Add(ic);


 foreach (DataGridViewRow row in DGV.Rows)
 {
   DataGridViewImageCell cell = row.Cells[1] as DataGridViewImageCell;
   cell.Value = (System.Drawing.Image)Properties.Resources.Icon_delete;
 }

using boolean data set, how we can do this?

I mean, value is true, then image will be 1.png, if value is false, image will be 2.png

Sagar Haridas Shinde 31-Mar-16 8:13am

Give Condition in for loop and according to this assign different two images for particular cell.
